Jessica Simpson Man Eating Watch

From a Jackass to a one-hit album wonder, pop diva Jessica Simspon has reportedly been keeping her body in top shape with steamy work outs, Celebrity Weekly, Star Magazine reports.

Dim lighting, a plush booth in the back and a tipsy Jessica Simpson downing vodka tonics as she cozies up to a hunky, dark-haired crooner. But on the night of Sept. 4, 2004, at the Whiskey Bar at L.A.'s Sunset Marquis Hotel and Villas, the studly singer that Jessica, 25, cozied up to was not her husband, Nick Lachey! Jessica was caught canoodling with Maroon 5's Adam Levine! "It was obvious that Jessica and Adam were very attracted to each other," an eyewitness who partied with the pair that night tells Star. "They were cuddled right up against each other, side by side, giggling and whispering romantically into each other's ears. Jessica was putting her hand on Adam's leg from time to time."
