Selena Gomez is growing up! Gomez has premiered the full vid for her latest single, "Love You Like A Love Song," and we're loving it! 18-year-old Selena is looking beautiful and striking an age-appropriate balance between sexy and modest.

This is the video that sparked Pink to send out some angry Tweets; she didn't like it when she spotted horses that had been dyed pink being used during filming. The horses are nowhere to be found in the karaoke-themed vid.

Gomez was in New York City for the premiere of her new movie Monte Carlo Thursday night -- check out what other celebs were there, including a huge surprise guest, after the jump!
