There are three kinds of celebrity friendships.
Some celeb best friendships are expected and make perfect sense: The Office‘s Jenna Fischer and Angela Kinsey, supermodels Kendall Jenner and Gigi Hadid, TV buds Busy Philipps and Michelle Williams, Friends stars Jennifer Aniston and Courteney Cox, High School Musical‘s Ashley Tisdale and Vanessa Hudgens, Saturday Night Live‘s Tina Fey and Amy Poehler.
Then we have the next tier of “didn’t really see it coming, but, sure, I get it” BFFs — like Justin Timberlake and Jimmy Fallon, Tobey Maguire and Leonardo DiCaprio, Jimmy Kimmel and John Krasinski, and Natalie Portman and Rashida Jones.
And then we have the completely unexpected, totally out-of-left-field celeb best friends. The ones that make you wonder how in the world they even met and what they could possibly have in common. But they clicked, and it’s the most magical pairing you’ve ever seen — like Jonah Hill and Ashley Olsen.
Here are some of our favorite celebrity friendships ever and how they all met.
