Jessica Simpson's naughty flirting session, while Nick looked away

If sources speaking to Celebrity Weekly, Star Magazine are spilling truth, pop diva Jessica Simpson's request for a private divorce should be denied. According to the source, a few months back, Jessica Simpson & Nick Lachey showed up at the L.A. nightclub Privilege, acting like all was well with their union. But while Nick, 32, had his back turned, a source says, Jessica, 25, got into some serious flirting with Trace Ayala, 25, Justin Timberlake's business partner. Trace put his hand on Jessica's leg and brushed it all the way under her skirt - not just once, but several times! "It was so obvious, anyone could have seen it," says the source. "But Nick just stood there with his back turned. He didn't seem happy to be there all night."

While , Nick probably deserved it for reportedly banging this and that girl, respect for the person you promised to be faithful to - should be a given in public.

Reports have linked Jessica to her Dukes of Hazzard co-star Johnny Knoxville, 34, skateboard star Bam Margera, 26, and most recently Maroon 5's lead singer Adam Levine, 26. Sources close to Simpson say that during the marriage Nick heard all the rumors and was warned about Jessica's nonstop flirting, he chose to believe his wife.

Now he's having serious doubts about whether Jessica was entirely honest with him. "I think Nick is pissed because he feels betrayed by Jessica and also because he feels like a chump," says a source. "He knows everyone is talking about the possibility that Jessica hooked up with other guys. While Jessica was out on the town, Nick was totally oblivious. It seems he was the last to know!"
