Warning: This article contains hypnotic twerking, booty-popping and sexy back-arching.
Shocking crowds with their steamy performance of 'Booty' at the 2014 American Music Awards, Jennifer Lopez proved her butt was best by sitting on Iggy Azalea's voluptuous rump … which is much more impressive than resting a champagne flute on your butt, Kim Kardashian. Check out that bootylicious moment above…
The pair's 'Partition'-inspired grind comes just hours after TMZ revealed the strict guidelines artists had to adhere to at this year's awards.
According to sources, JLo and Iggy were not allowed to show their "cracks" while on stage, with absolutely "no rubbing" or "spanking" allowed after Miley Cyrus' controversial twerk at the MTV VMAs last year.
Yep, we're glad the girls didn’t stick to the rules.
