Cody Simpson recently posted a pic with Jason Derulo and called him one of his "mates," which totally surprised us! We had no idea that they even knew each other, let alone that they were actually friends.
The discovery inspired us to go digging for a few more super surprising celeb besties. Click through to see what we found and let us know which ones shock you the most in the comments!
Harry Styles and Kelly Osbourne
We had no idea Kelly and Harry were so close! Since Kelly is good friends with Taylor Swift, we wonder if she's like the female version of Ed Sheeran and is keeping the peace between those two.
