Jennifer Lopez just won't stop being fierce ahead of AMAs gig...

That ruching design on J.Lo's ass is lethal, but overall, her body is slaying more than anything.
I have yet to see a 20-year-old with her body. It's insane, and that dress is fire! I would seriously raid her bins just to try and find the secrets to her diet and fitness regime. Jenny was spotted making her American Idol rounds in California yesterday. Chick is clearly all glossed up and ready to host the American Music Awards tomorrow night.

Whilst we're here, check out her brand new L’Oréal Paris commercial:
