The "Spring Breakers" star announced her Movie Awards performance during a chat with MTV "After Hours" host Josh Horowitz, saying, "I think it's really cool because I got to take a year off of music and really be a part of great movies and work with great people, so I thought it would be perfect that I go into music again through MTV and the Movie Awards. I'm so stoked." Needless to say, we're stoked TOO. Like, x1,000. We've only been reading about Selena's upcoming new tunes for-EVER, and we can only pretend to be patient for so long!
