Kim Kar-who? Wednesday belonged to J.Lo’s booty.
On a night many huge names -- including Lady Gaga, Beyonce, Carrie Underwood ... heck, even Spiderman! -- appeared on American Idol’s season finale, it was the show's own Jennifer Lopez who commanded the limelight, with an amazing derriere display that left the audience hot and bothered.
The 41-year-old On The Floor singer danced while her husband, I Need To Know singer Marc Anthony, performed.
At one point, she launched into a booty-shaking trance that lasted a whopping 15 seconds, showing she's still got some of her old Jenny From The Block swag.
Fun fact: J.Lo has had four number one hit singles in the U.S. -- If You Had My Love, Ain't It Funny, I'm Real and All I Have.
