Justin Busted With Co-star! Pregnant Jessica's World Crashes

He has some explaining to do at home

Actress Jessica Biel couldn’t have looked more miserable as she ran errands in Los Angeles last week, days after her husband Justin Timberlake was caught cosying up to another woman.

Insiders claim the actress – believed to be four months pregnant with her second child – was “devastated” when photographs and video footage hit the internet of Justin holding hands with his attractive co-star Alisha Wainwright.

Now, the couple’s seven-year marriage – once admired as one of Hollywood’s strongest – is hanging by a thread and Jessica has taken refuge in the home of her ex-boyfriend, Captain America star Chris Evans.

“Jessica fled to Chris’ house as soon as the news broke,” a source close to the The Sinner star reveals. “Chris was a huge part of Jessica’s life for five years and she feels safe with him. She’s told Justin she needs space and time apart from him while she processes it all.”

While Jessica has bravely faced cameras with her wedding ring still on, insiders say that behind the scenes she was in “a state of complete shock” when the images emerged of Justin, 38 – in New Orleans to film indie movie Palmer – drinking at a bar and getting touchy-feely with Alisha, 30.

The “Cry Me a River” singer sat with his hand cradling Alisha’s and at one point he guided the Raising Dion actress’s hand to his knee and stroked it.
