Vanessa Hudgens appeared on Jimmy Kimmel Live! last night to promote her new flick Spring Breakers, and we're loving her sexy orange jumpsuit!

Within seconds of sitting down, Jimmy went straight for the topic that everyone's talking about ... Vanessa's threesome scene with co-stars Ashley Benson and James Franco.

"It was like the weirdest thing ever," she said. "I mean I think just as an actor in general thats like such an uncomfortable thing to do. And so me and Ashley … its like, a threesome, so I had her, and we're like trying to get ready for it and we're just like, 'This is going to be fine, right?' And we were giving ourselves so much anxiety that we were, like, so much more nervous by the time we actually got to set … it was just bad."

Nessa chats more about James and how her family reacted to the film ... check out the rest of the interview below!
