The former couple, which dated on and off from 2010, both hit the red carpet separately at the top fashion gala on 4 May (15), and it appears Hudgens was instrumental in helping her Spring Breakers co-star keep her distance from Bieber as they partied the night away.

During an appearance on U.S. talk show Watch What Happens: Live on Thursday (21May15), Hudgens addressed the situation by stating, "She's one of my best friends and you just want to have your girlfriend's back, so that's what I did. We didn't, like, try to avoid him or anything. (But) I mean, no one really wants to see your ex-boyfriend. We had a lot of fun."
