Jennifer Lopez: Hard-Core

Jennifer Lopez sweaty with no makeup after a cardio workout still looks hotter than most people do on a Friday night out.

J Lo's twins Max and Emme turned 8 on Monday so she was likely burning off the birthday cake or just firming up her best asset.

Her abs are definitely giving her ass a run for the money.
