Surprising Celebrity Friendships

Jessica Williams and J.K. Rowling

When J.K. Rowling first started following Williams on Twitter, she didn't believe it (then got tweet-shy, because, you know—it's hard to perform when your audience includes a best-selling author). Then Rowling *slide into the DMs,* where a beautiful friendship was born. Watch Williams tell it above.

Katy Perry and Neil deGrasse Tyson

Following the release of Katy Perry's new album Witness, Neil deGrasse Tyson shared a photo with the pop star on Twitter. He wrote, "Was @katyperry's personal astrophysicist on #KPWWW for an hour... We all should be as curious as she." It certainly looks as though the pair hit it off.

Matt LeBlanc and Emilia Clarke

They're stars of two of TV's biggest franchises of all time but have somehow never met. And now that they have, the Friends and Game of Thrones fandoms are colliding like never before.That's right, Matt LeBlanc (a.k.a. Joey) and Emilia Clarke (a.k.a. Khalessi/Mother of Dragons/Breaker of Chains, etc.) are now buds. The pair met at The Graham Norton Show and Clarke posted this super cute picture of the pair backstage on her Instagram.

The Kardashian Fam, Courteney Cox, Isla Fisher, and Sacha Baron Cohen

There's a lot happening here. In a picture posted to Instagram, Kim Kardashian details this particular night: "This was the moment right before Sacha showed us the CRAZIEST scene from The Brothers Grimbsy We laughed so hard we cried!" she wrote. Just friends hanging and watching movies with friends, nothing to see here.

Instagram

Britney Spears and A.J. McLean of Backstreet Boys

Britney has always been considered to be solidly on Team NSYNC given the tight ties the singer shared with her '90s pop star peers, and one Justin Timberlake in particular, but your childhood as you knew it is about to get totally rocked. Britney Spears posted a photo on Instagram in which she's hugging A.J. McLean—as in A.J. of the Backstreet Boys—with the caption "Huge confession... biggest @backstreetboys fan! Tonight was truly a dream for me." It's okay Britney—we couldn't choose between NSYNC and Backstreet Boys either.

Instagram

Mariah Carey and Will Ferrell

After befriending Beyoncé (next slide), Mariah Carey has unveiled yet another surprising celeb friendship: this time, with Will Ferrell. The comedian attended the Mariah #1 to Infinity show in Las Vegas, where the two had the chance to hang out backstage. MC documented the special moment on Instagram, writing: "Shake and bake !! Thank you for coming to my show last night !! #elf forever !!" The "Obsessed" singer even did Ferrell's makeup, which you can check out here.

Beyoncé and Mariah Carey

Mariah Carey and Queen Bey hanging out together? That just might be too much for our diva-loving hearts to handle. The pair of living legends spent time together at an event for the HeartView Global Foundation in L.A.—which was graciously documented for us via MC's Instagram account. "Two girls, one cause," she captioned the pic.

Harry Styles, Kendall Jenner, Ellen DeGeneres and Portia De Rossi

On New Year's Day, Harry Styles and Kendall Jenner (who are apparently *so* back on) decided to turn a Caribbean yachting trip into a double date by inviting Ellen DeGeneres and her wife, Portia De Rossi, along for the ride. Here, the foursome is seen living their best lives ever and redefining #SquadGoals for 2016.

Instagram

Blake Lively and Taylor Swift

Who knew?! The two blondes hung out in Australia—where Swift took her entire crew on vacation—and clearly spent some time hanging out with kangaroos and jumping for joy. "Yesterday was such an amazing day off—roller coasters, kangaroos and LOLs with @blakelively 🌷. "See you tonight, Adelaide!" Swift captioned the photo. (New squad member alert.)

Instagram

Bob Saget and Macaulay Culkin

After a Broadway performance of Hand to God, two of the people who defined your childhood took a selfie together in Times Square. P.S. Bob is also pals with Real Housewife Carole Radziwill.

Instagram

Jennifer Aniston and Justin Bieber

Biebs posted this selfie with the actress to Instagram with no caption and no context, which makes the pairing *that* more interesting. WHAT DO YOU MEAN, JUSTIN? #Friendship

Twitter

Drake and Ruby Rose

New besties alert! Drake and Ruby Rose both partied at Kendall Jenner's birthday, and hit the photo booth a couple of times—with Drake posting to his own account and Ruby Rose to hers—proving their newfound friendship is definitely a thing.

Instagram

Jennifer Lopez and Kylie Jenner

Big Hollywood parties bring out the most unexpected of celebrity friends—but this one kind of makes sense. At last night's birthday celebration for Balmain creative director Olivier Rousteing, Kylie Jenner partied and selfied with Jennifer Lopez, who could arguably be the Kylie Jenner of the early 2000s. Think about it: a bootylicious figure and a wardrobe that shows it off, a penchant for plunging necklines, a tendency to date rappers and make headlines in the process. Jennifer Lopez is basically the OG Kylie Jenner.

Instagram

Chrissy Teigen, John Legend, Jessica Alba, and Cash Warren

The couples had a Halloween-themed double date last night at the Los Angeles Haunted Hayride. "We had a fright tonight @lahauntedhayride," Alba wrote on Instagram, accompanied by an adorable group shot. While hashtag squad goals is a bit overused at this point, there's never been a more appropriate descriptor for such a delightfully unexpected celeb hangout sesh.

Kourtney Kardashian and Justin Bieber

Kourtney Kardashian was spotted out to dinner with none other than Justin Bieber. Is she taking a page from Scott Disick's dating playbook—or is she just befriending the much-younger pop star? Hmmm...

Britney Spears

Britney Spears and Kate Hudson

So this happened. Over the weekend, Kate Hudson hosted a chill game night—until Britney crashed (JK, Hudson totally gave her a ring) and the two dominated the night. Monopoly, Scrabble, Cards Against Humanity, no one was safe from these bombshell blondes.

Jennifer Garner and Gwyneth Paltrow

The duo (who both share a history with Ben Affleck) hung out at the charity telethon event for Think It Up in Santa Monica, California, a charity aimed at improving education in America by inspiring public school students to turn their passions into projects.

Instagram

Ruby Rose and Ellen Page

They're not just friends—they're *best* friends! Ruby had already mentioned that Ellen was one of her gang, but this Instagram from Ruby makes everything official in our eyes. Captioning the snap: "When your best friend is the most talented, funny, beautiful, generous, humble human being it's hard to not smile until it hurts. Ellen, I am so proud of you and will always be grateful for everything you are and will always be to me." Sorry Tay, I want in on this squad.

Instagram

Kim Kardashian and Serena Williams

We had no clue about this until 1) Kim posted a pic of them sipping on some pre-quarterfinals tea Monday and 2) we subsequently found out they've been friends/photographed together since 2006. Who knew?

Nick Jonas and Jay Z

Well, we definitely didn't see this one coming. The rap legend and the "Jealous" singer hung out backstage at the Budweiser Made in America Festival—leaving us very excited (but also just a *little* confused) about this budding bromance.

John Mayer and Bob Saget

File this under: most unlikely bromance ever. The singer-songwriter and the Fuller House star had dinner at Craig's in Los Angeles—and judging from this pic, Saget is much more thrilled about their guys' night than Mayer.

Instagram

Taylor Swift and Ruby Rose

It happened. Then Ruby Rose remixed "Style," and Taylor welcomed her to the stage, along with the hologram of Maya Angelou.

Instagram

Lady Gaga and Barbra Streisand

Lady Gaga and Barbra Streisand strike a pose in this Instagram snapshot. So much diva power in just one photo.

Instagram

Tavi Gevinson and Kris Jenner

In the latest episode of 'Random Friends You Didn't Know Kris Jenner Had', we find Tavi Gevinson. The style blogger 'grammed a photo of herself with the Kardashian matriarch last night. Oh, and we see you photobombing back there, JLaw.

Instagram

Kris Jenner and Jennifer Lawrence

The reality star and self-described 'momager' posted this photo with Lawrence for the actress's birthday, the two of them caught in the act of cuddling up with a book. Who knew they were so, well, close?
