Whoa, Jennifer Lopez!

The sexy singer stunned Thursday night (Feb. 20) at the "American Idol" after-party held at the Fig & Olive in West Hollywood, Calif., wearing a little black dress with strategic cutouts and sky-high black heels.

Lopez, 44, celebrated with fellow judges Keith Urban, Harry Connick Jr. and host Ryan Seacrest after narrowing the "Idol" competition down to 13 contestants.
