American Idol Names Top 13 Finalists

The top 13 American Idol finalists have been announced. The judges got to pick three wild cards, and Jennifer Lopez says it was a tough decision.

"It was awful. It was so tough, it was so hard, even up until the very last second it was like, wait a minute, we really didn't know who to choose," Lopez said.

INSIDE EDITION caught up with her at the party celebrating the 13 finalists. She was wearing a sexy outfit, short shorts and a midriff-baring shirt.

Lopez debuted her sexy new music video for her song "On the Floor" at the party.

In the video, Lopez wears a skintight body suit, which highlights what great shape she is in. She proves she is one of the hottest 42-year-old moms around.
