This year’s American Music Awards was all about the performances. Sure, there were awards handed out, but the real draw centered around the onstage acts. Host Jennifer Lopez opened the show by belting out her classic “Waiting for Tonight” and then put on an epic dance number to some of 2015’s top tracks. There was a mini Clueless reunion as former co-stars Alicia Silverstone and Jeremy Sisto introduced Gwen Stefani’s performance. Harrison Ford rallied the audience before the Star Wars spectacular performed by Pentatonix and Celine Dion blew the crowd away with her touching tribute to Paris. When it came to fashion, celebs decided to flash a decent amount of skin. Even though quite a few stars skipped the red carpet, there were plenty of eye-catching moments, from Gwen’s over-the-top black sheer gown to Carrie Underwood’s flowing cape and Demi Lovato’s retro statement.
