It's been more than 10 years since Jennifer Lopez stunned us with her incredible abs in the "Jenny From the Block" music video, but girlfriend's still got it.

The sassy singer attended the "American Idol" after-party in Hollywood on Thursday and flaunted her toned tummy in a sexy black cutout dress.

Doing her signature open mouth pose, the 44-year-old mom worked the carpet in the Cushnie et Ochs stunner which featured a halter neckline, a pencil skirt and an open back.

Giuseppe Zanotti pumps, gold cuffs and a topknot completed the gorgeous look which drew in admiring glances from her "Idol" co-judges, Keith Urban and Harry Connick Jr. (Who could blame them?)
