Jessica Biel Cheating on Justin Timberlake?

While the cat is away, the mice will play. While Justin Timberlake is touring in Europe, girlfriend Jessica Biel is getting cozy with her ex-boyfriend Chris Evans according to Star.

Biel ran into Evans while attending a wedding reception last Saturday and was spotted holding hands and making out with him. Then they departed together to an unknown location.

“Sparks were flying,” says an eyewitness. “It looked as if they were completely absorbed with one another. From what I could see, Jessica hardly left Chris’ side. They were holding hands and cuddling all night - even trading little kisses! They sat together and even walked to the bathroom together. Everyone was shocked because we thought she was dating Justin. But it didn’t look like she was thinking about him that night - she was consumed with Chris…”

Evans rep states the two are “just friends,” but a source who saw the two seems to think they left to go have sex.
