What's more ridiculous than Jennifer Lopez and Iggy Azalea's "Booty" video? Watching the duo "shake that" live.

American Music Awards red carpet: See all the hottest looks 

J. Lo and Iggy closed the American Music Awards with a frenetic performance that featured much gyrating and a number of skimpy outfits that, understandably highlighted Lopez's most famous asset.The performance, which barely made use of Azalea at all, ultimately devolved into a long, high-energy dance break that, while less unabashedly sexy as the music video, was still wildly entertaining. Watch it below.



Iggy spent plenty of time on stage, however. Besides performing her own hits "Fancy" and "Beg For It," she also won two awards, Favorite Artist Rap/Hip Hop and Favorite Album Rap/Hip Hop. "This award is the first award I've ever won in my entire life, and means so much to me that it is for best hip-hop, because that's what inspired me to move to American and pursue my dreams," the Aussie artist said. "It's what helped me when I was a teenager to escape and to get through my life and to better times."

One Direction and Katy Perry were the big winners, with each taking home three trophies. The British boy band kicked off the night's accepting the award for Favorite Band, Duo or Group. "America feels like a second home to us... it's been amazing how well we've been received," Liam Payne said. The group also won Artist of the Year and Favorite Album Pop/Rock.

Perry, who accepted her awards via satellite from Australia, nabbed wins for Favorite Artist Adult/Contemporary, Single of the Year (for "Dark Horse") and Favorite Female Artist Pop/Rock.

The other big win of the night was to 5 Seconds of Summer who took home the coveted New Artist of the Year trophy.
