Jennifer LopezAs the saying goes, if you've got it, flaunt it. And boy does Jennifer Lopez have it.

The 'American Idol' judge showed off her svelte figure at the Best Buy in Los Angeles yesterday, arriving in a midriff-revealing tube top that highlighted her toned tummy. The barely-there "shirt" was awfully skimpy for a typical afternoon, but JLo has never been one to blend in.

The mother of two was feeling very generous as she chatted with her adoring fans, even taking time to record voicemail messages for a lucky few, saying: "This is Jennifer Lopez, please leave a message after the beep."

This Jill-of-all-trades may have a jam-packed schedule, but clearly she isn't missing any beauty sleep.
