Katy Perry and Kristen Stewart
Katy Perry and Kristen Stewart's friendship fallout seemed to be centered on one thing: Robert Pattinson. Kristen and Robert broke up in May 2013, and Katy, who is friends with both Twilight stars, was reportedly forced to choose sides. While Katy and Rob continued to hang out after his breakup with Kristen, rumors spread that the two were more than friends. In an effort to clear the air and save both of her relationships, Katy took things into her own hands. She revealed in the September 2013 issue of Elle UK, "I sent her [Stewart] a text message saying: 'I know you've seen all this stuff, but you know I would never disrespect you. I'm not that person. I'm just trying to be a friend to him, but it is unfortunate that I do have a set of tits.'"
While it hasn't been confirmed whether or not Katy and Kristen have officially patched things up, you have to admire Katy's can-do attitude when it comes to setting the record straight.
