Jennifer Lopez and Iggy Azalea closed out the 2014 American Music Awards with a salacious performance of their collaborative hit 'Booty' -- and, well, it's a good thing they ended the night because we're not sure who else could've topped them.

The performance started off with J. Lo showing off her most famous asset in a black and white bodysuit, while Iggy donned her own silver one-piece. There was plenty of gyrating and booty shaking to go around, and both ladies totally killed it.

Our favorite part? It’s a toss-up between that hilarious booty call bit between J. Lo and one of her dancers, and a serious appreciation for J. Lo’s super speedy wardrobe change. She slipped into an all red, sparkly bodysuit with a neckline so low it was totally channeling that Versace dress J. Lo wore to the 2000 Grammys.

It was definitely the best way to end an evening full of amazing performances!
