Jennifer Lopez Shows Leg At 'American Idol' Finalists Party

Although Jennifer Lopez stepped out Thursday night to celebrate the 13 "American Idol" finalists, we have a feeling that all eyes were on the the sequin-clad stunner.

The 42-year-old mother of two stole the show in a gold sequined minidress, showing off her signature gorgeous gams. With Lopez's right leg outstretched, could she be trying out Angelina Jolie's now infamous red carpet pose?

Fellow judges Steven Tyler and Randy Jackson and host Ryan Seacrest flanked the beauty as they posed for photographers, basking in the glory of having narrowed down the search for the next "American Idol."

But the night wasn't all smiles for Lopez. During contestant Jeremy Rosado's performance, the "On The Floor" singer broke down into tears saying, "I believe in this kid. I believe in Jer Bear. I think he's got one of the most beautiful voices I've heard."
