15 Unexpected Celebrity Friendships of 2013

X-Men actors Ian McKellen and Patrick Stewart may be enemies on the big screen, but they're BFFs in real life. Magneto and Professor X actually first met when acting in the Royal Shakespeare company in the 1970s, but started to really bond on the X-Men set. The pair showed the world their impossibly adorable bromance over Twitter this year while they both performed in two Broadway plays together, Waiting for Godot and No Man's Land. Their selfies were all over New York: They wore bowler hats! They ate corn! They went to Madame Tussaud's! They posed by the Stonewall memorial! They went jogging! They drank beer! They went on top of the Empire State building! They put two thumbs up in front of some trash! The two are so close that McKellen even officiated Stewart's wedding to singer-songwriter Sunny Ozell this year.

Mckellen and Stewart may have been "homies forever," but they aren't the only famous best friends. We saw all types of new friendships blossom this year, for better or worse — and some of them were completely unexpected. But hey, everybody needs a bestie, even celebrities. So here's some of the more surprising friendships that came out of 2013. Feel the love.

Sandra Bullock and Melissa McCarthy

It was a beautiful friendship story that we all got to see play out on the big screen. Funny girl gets cast in blockbuster movie. Girl meets serious actress co-star. Girl stabs co-star in the leg in the movie. Girl and girl become true besties for life. Don’t believe us? Just ask Paul Feig, who says that since making The Heat, the pair have become “inseparable.” They even dressed up as fishermen and took their kids trick-or-treating on Halloween!

Kristin Cavallari and Gretchen Rossi

This one isn’t as surprising as it is weirdly ironic. The former star of Laguna Beach hanging out with the current star of Real Housewives: Orange County? Just how small is Orange County, anyway? Apparently small enough for the two to go out for dinner with a few celebrity stylists. Sing it with me: Californiaaaa…

Taylor Swift and Ed Sheeran

Platonic relationships are pretty rare, even in Hollywood. Despite the obvious dating rumors, the two say that they’re just close friends and they’d rather have it stay that way. And with friends like these, why wouldn’t you? Swift recently surprised Sheeran by appearing with him onstage at his concert in Madison Square Garden. Meanwhile, the only way your friends remember your birthday is through Facebook.

Katy Perry and Kate Hudson

Turns out, these ladies have more in common that just their names. (Perry famously had to change her last name from Hudson to distinguish herself from the actress.) Instead of going out together, Perry and Hudson stay in and have game nights. Who knows how the two even met, but Hudson is apparently a pretty good friend to have…

Kate Hudson and Lea Michele

Few people have had a more difficult year than Lea Michele. The actress and singer’s boyfriend, Cory Monteith, recently died from a drug overdose. But fortunately, Michele had friends like Kate Hudson, who she met on the set of the last season of Glee. When Michele’s house was swarmed with reporters during the tragedy, Hudson told her she was welcome to stay at her place. That’s the test of true friendship, y’all.

Iggy Azalea and Angel Haze

These lady rapper buds have always showed their love over Twitter, but this year they proved it by covering Jay-Z and Kanye West’s “Otis” in concert. Since they’re both female rappers, most people expected them to have some kind of public beef (because ladies be fightin’, duh), but these two proved everyone wrong by becoming BFFs.

Amy Poehler and Mindy Kaling

This isn’t as surprising as it is exciting — these funny ladies already worked together briefly on Saturday Night Live. But really, this is the friendship of your dreams. And they’re taking shots. It’s like a puppy delivering you a box of chocolates. That’s how great this photo is.

This one, however, is a bit more surprising. But it’s a perfect pair, nonetheless — the queen of rom-coms and the number one rom-com fangirl, together at last. No wonder they want to work together!

Margaret Atwood and Alice Munro

The Canadian writers have been good friends for years. But they got to celebrate it this year when Alice Munro won her Nobel Prize. Because really, what’s a better way to celebrate than with the one thing that’s always there for you, wine (oh yeah, and your best friend)?

Katy Perry and Robert Pattinson

The cupcake princess and the glittery vampire from the wrong side of the tracks. Really, who would’ve thought? But we all got to witness their friendship this year when the video of the two drunkenly singing Boyz II Men’s “I’ll Make Love to You” at karaoke surfaced. Of course, rumors of romance persist, but right now the two seem to be just friends.

Lena Dunham and Claire Danes

The two bonded this year on the red carpet at the Emmys (Danes being nominated for Homeland and Dunham being nominated for GIRLS) and have stayed friends ever since. Sure, it may seem unexpected now, but we’d bet that Dunham totally looked up to Danes during her alt heyday in the ’90s.

Lily Collins and Ciara

The “Body Party” singer and the actress of Instruments: City of Bones struck up a friendship during Paris Fashion week this year and even went out to dinner together. Who knows what they even have in common, but one thing’s for sure: they can both smize like no other.

Kid Cudi and Michael Bolton

The rapper’s mom had always been a huge fan, so he got Bolton to record on his song “Afterwards (Bring Yo Friends).” The two hit it off in studio, and Cudi even said Bolton was like “the uncle I never had.”

Lindsay Lohan and Charlie Sheen

Well, they certainly have, uh… similar world views. The two met on the set of Scary Movie 5 late last year, and Sheen seems to be acting as a sort of father figure to Lindsay, even going so far as to pay off her $100,000 tax bill. It’s almost sweet, in a way… okay yeah, there’s no way this can end well.
