28 Unexpected Celebrity Couples We Never Saw Coming

They were in a relationship? They may not make sense to the uninitiated, but celebrity romances are often intriguing to those who follow them. Celebrity relationships in 2021 have taken some surprising turns, and this is no exception. To begin with, we were shocked to learn of Kourtney Kardashian and Travis Barker's frenzied, PDA-heavy romance. Even more shocking was that Megan Fox and Machine Gun Kelly were engaged (neither did Pete Davidson). Couples that meet by chance are nothing new in the year 2020. You may have forgotten about some of the craziest celebrity couples from the '90s and beyond, but they've been around for a long time.

In Hollywood, nothing is sacred, least of all your romantic relationship. Miley Cyrus and Liam Hemsworth's breakup has spotlighted celebrity love lives, and it takes a unique breed of celebrity to keep their love lives out of the spotlight. Still, a few celebrities have managed to keep their romances out of the public eye.

Stay with us for a list of famous couples we hardly knew were together if you're trying to expand your celebrity relationship radar. We've rounded up some of the most surprising celebrity pairings, from the '90s to the present day, that we're still trying to wrap our heads around.

1. Bill Hader and Anna Kendrick

Bill Hader and Anna Kendrick had been dating for almost a year, and no one knew! The two have been "quietly" dating, according to reports, and are said to be very happy with each other. A source told the publication that "they are both very private people, and with the pandemic, it was simple to keep it quiet." "Since they're hysterical, they must constantly make each other laugh. "She's in a great mood." On the 2019 Christmas film, Noelle, Hader, and Kendrick worked together again.

2. Travis Barker and Kourtney Kardashian

Kourtney Kardashian's engagement to Blink 182's drummer would make us believe you were writing fanfiction. Even if you don't like them, Kim Kardashian and Travis Barker are here to stay and share a lot of PDA in 2021.

3. Blake Shelton and Gwen Stefani

Nobody expected Gwen Stefani and Blake Shelton to get married in 2021, despite our suspicions that love was in the air on The Voice. We're still baffled how this former ska princess and her country beau manage to have a date night at their home.

4. Megan Fox and Machine Gun Kelly

Both Megan Fox and Machine Gun Kelly's romance and their double dates with Kourtney Kardashian and Travis Barker are utterly bizarre. Despite their eye-catching red carpet looks, the two have a complex personal life that includes anything from controversial interviews to blood vial necklaces.

5. Taika Waititi and Rita Ora

The news of Taika Waititi and Rita Ora's romance has probably caught you off guard. That first date was confusing because we don't know how these two ended up together or what happened on it. But they're still one of the cutest couples to emerge from 2022, nearly a year later.

6. Ben Affleck 2.0 and Jennifer Lopez

Jennifer Lopez and Ben Affleck rekindled their romance in 2002, something none of us could have predicted. We always wanted Bennifer 2.0, but we never believed we'd get it. We're looking forward to Bennifer's arrival in 2021.

7. Dave McCary and Emma Stone

After Stone and McCary's engagement, the public becomes aware of their romance. However, the two have been dating since December of 2016. On Saturday Night Live, their paths crossed when McCary directed Stone's sketch while she was a guest host.

It was only at the SAG Awards in January of this year that the two finally made their public red carpet debut as a couple. It's been reported the couple secretly married after they announced their engagement on Instagram in December of that year.

8. Suki Waterhouse and Robert Pattinson

As one of the most secretive off-screen relationships, Waterhouse and Pattinson have been linked since 2018. They've dated Taylor Swift and Joe Alwyn in the years since.

Despite never openly addressing their relationship status, the couple has begun to fuel engagement rumors after attending Waterhouse's birthday party in January 2020 as a couple.

9. Bill Hader and Rachel Bilson

After a trip to a Starbucks in Tulsa, Oklahoma (Hader's hometown), rumors of a romance between the Saturday Night Live alum and The O.C. actor began circulating in December 2019. Then, at the Golden Globes a month later, they shocked everyone by walking the red carpet together for the first time. The duo, who first met in the 2013 film The To-Do List, has decided to keep their relationship a secret for the time being.

10. Alicia Vikander and Michael Fassbender

In November 2014, Vikander and Fassbender were first linked, but they were seldom ever seen together again. The couple, who met on the set of the romance drama The Light Between Oceans, is expected to wed in October 2017 in a small ceremony on the island of Ibiza. The couple's embrace after Vikander won the Academy Award for "Best Supporting Actress" in 2016 proved their love, even if there have been few updates since then.

11. Hedlund and Roberts

Garrett Hedlund and Emma Roberts' new romance remains a closely guarded secret despite their prior high-profile relationships with other celebrities (Kirsten Dunst and her American Horror Story co-star and ex-fiancé Evan Peters). Even though they've been dating since March 2019, they've only been spotted out for informal dinners and coffee dates in public.

12. Jordan Peele and Chelsea Peretti

After meeting on Twitter in 2013, Brooklyn Nine-Nine actress Chelsea Peretti and Get Out filmmaker Jordan Peele have been dating ever since. Their dog was the only witness to their 2015 engagement and 2016 wedding after two years of dating. He and his wife gave birth to a baby named Beaumont Gino Peele in July 2017.

13. Robbie Arnett and Elizabeth Olsen

Most of us were shocked to learn that Olsen was even seeing someone when she announced her engagement to musician Robbie Arnett in July 2019. For the past three years, she's been engaged to Milo Greene's lead singer, but she prefers to go it alone on the red carpet.

14. Benji Madden and Cameron Diaz

Benji Madden, a tattooed musician, and Cameron Diaz, a blonde movie star, may seem like an odd couple, but the two are clearly in love. After only seven months of dating, Diaz proposed, and the couple wed in 2015 in a private ceremony at Diaz's house. They are rarely seen in public, other from infrequent social media tributes.

15. Jodie Smith and Joshua Jackson

Many were unaware of Jackson and Smiths' connection until they were sighted getting married in August 2019. According to reports, the two apparently met at Usher's 40th birthday party in 2018 and have since become one of Hollywood's hottest couple duos. As a result, they were able to tie the knot and have a child in April 2020.

16. Cobie Smulders and Taran Killam

While most people recognize Cobie Smulders from the iconic program How I Met Your Mother, some may not recall Taran Killam's cameo there. The relationship between her then-boyfriend at the time and these two has been very private.

We've recently begun to see the couple's power-couple presence regularly, having married in 2012.

17. Max Minghella and Elle Fanning

Although they have never confirmed their relationship, Fanning and Minghella's public attendance at the 2019 Met Gala screamed volumes. Fanning has called Minghella "a wonderful buddy" in interviews since they met on the set of their upcoming film, Teen Spirit, in July of last year. Despite this, they've been seen holding hands several times, suggesting they're more than simply friends.

18. Elon Musk and Grimes

It may seem strange that the 31-year-old electric guitarist and the 48-year-old Tesla and SpaceX entrepreneur have been together for nearly a year, but their romance began on Twitter. Tesla CEO Elon Musk and Grimes' "wildly aesthetic imagination and hyper-focused work ethic" were praised in a Wall Street Journal interview in May of 2019.

In May 2020, the couple became parents for the first time. It's safe to say that the birth of their son X A-Xii put their relationship in the public eye because of the contentious name they gave him.

19. P. Hermann and M. Hargitay

Indeed, Charles from Younger and Olivia Benson from Law and ' Order: Special Victims Unit have been married since 2004. In 2002, while Hermann was a guest star on Law and ' Order: Special Victims Unit, they met and have married ever since.

20. Daniel Craig and Rachel Weisz

Daniel Craig and Rachel Weisz have managed to keep their eight-year marriage a secret even though they are both high-profile actors. Their non-professional lives are kept out of the public view by paparazzi photographers, even if they do attend red carpet events together on occasion. In September 2018, the couple welcomed their first child together, a baby girl, into the world.

21. Dave Franco and Alison Brie

People are still surprised to learn that Alison Brie and Dave Franco, who have been together for nearly a decade, are still together. People are even more surprised to learn about their origins. They attended Mardi Gras and engaged in "48 hours of drugs and sex [and] a lot of making out," according to Sun U.S. After then; Brie claimed that Franco had sent her a secret message inviting her to Paris.

22. Emilia Clarke and Seth MacFarlane

No one will ever forget Seth MacFarlane and Emilia Clarke's whirlwind courtship on Family Guy. From 2012 to 2013, there was a period when this occurred. They broke up because of the distance, and it's still unclear how these two met in the first place.

23. Channing Tatum and Zoe Kravitz

When it comes to our date night, we have many questions. First, Zoe Kravitz and Channing Tatum were rumored to be dating in 2021. Then, they promptly dispelled the speculation. In August, though, they were resurrected, and the two have been together ever since. There is a lot of uncertainty about what will happen next.

24. Adam Brody and Leighton Meester

Who would have predicted that Adam Brody and Leighton Meester would be married and have children? Arlo Day, 6, and an unnamed son were born to them after their 2014 wedding.

25. Taylor Swift and Tom Hiddleston

No one anticipated Taylor Swift to take a love detour into the Marvel Cinematic Universe with Tom Hiddleston. After just dating for a short time in 2016, fans were torn on whether or not to ship the couple.

26. Kat Dennings and ' Andrew W. K.

The alt-couple we didn't realize we needed is WandaVision's Kat Dennings and Andrew W.K., the self-described "God of Partying." We were taken completely off guard when they announced their engagement on Instagram, and we're still trying to catch up with this couple.

27. Lizzy Caplan and Matthew Perry

This was not what we had in mind when we thought of a Mean Girls/Friends mashup. Why are we only now learning that Matthew Perry and Lizzy Caplan dated for five years, from 2006 to 2012? We've never seen anything like this before, but we're fine with it.

28. John Mulaney and Olivia Munn

News that comedian John Mulaney was divorcing his longtime wife and expecting a child with actress Olivia Munn became one of the greatest scandals of 2021. Many people are still opposed to the new parents being together because of how out of the blue this connection appeared.
