Jessica Biel, the wife of Justin Timberlake, is reportedly demanding that he take a lie detector test after he was caught canoodling with Black actress Alisha Wainwright.

"She's gone from being in total shock to being livid and demanding to know what the hell is going on here," an insider told Radar.

Justin was caught holding hands with Alisha, and Alisha's hand was seen rubbing his leg. He was later found on camera, leaving the actress' trailer alone.

"(Biel's) trusted him in the past but this is beyond any level of acceptability, even if he was totally bombed that night," the source told the entertainment outlet.

"She may even put him through a lie detector test," the source said.

Both Justin and Alisha have denied that they have cheated. Justin reportedly had too much to drink and they say they are just friends.

"He's really humiliated [his wife] and she's sick to her stomach about the whole incident."
