AceShowbiz - Jessica Biel seemingly doesn't entirely believe husband Justin Timberlake's claims about his innocent relationship with co-star Alisha Wainwright. According to a new report, Jessica is "massively on the warpath" following the PDA scandal.

"She's gone from being in total shock to being livid and demanding to know what the hell is going on here," a source speaks to Radar Online of "The Sinner" star. "(Jessica's) trusted him in the past but this is beyond any level of acceptability, even if he was totally bombed that night."

Although previous report suggested that Justin and his sexy "Palmer" co-star were just "friends," Jessica allegedly has been grilling everyone she knows in her husband's inner circle because she wants answers. The source goes on saying that "she may even put him through a lie detector test."

Meanwhile, Justin was photographed looking worried on the filming set on Monday, December 2. Donning a T-shirt, jeans and black jacket, Justin appeared somber between scenes. In the photos obtained by Radar Online, he could be seen texting, talking on the phone and chewing on a toothpick.

Justin and Jessica's relationship reportedly went south after the former was caught getting a little too close with Alisha at a bar in New Orleans on Friday, November 22. She was seen resting her hand on the former NSYNC member's knee.

In another photo, meanwhile, the "Say Something" singer was seen holding the 30-year-old actress' hand on his knee. His wedding ring was noticeably absent from his finger.

A rep for Alisha also played down the hookup speculation. "There is no validity to this speculation. They are currently working on a project together. Members of the cast and crew were all together," the rep stated.
