Sandra Bullock has reportedly escaped to her pre-marital home in the wake of husband Jesse James' alleged infidelity.

According to TMZ, the Academy Award-winning actress has been living at the Hollywood Hills home she purchased prior to marrying the Monster Garage star, who is accused of having multiple affairs.

The celebrity gossip site said Bullock, 45, arrived at the home last Wednesday and hasn't since returned to the Orange County residence she shares with James. Since arriving, the Blind Side star has rarely left the home. On one occasion when she did, Bullock managed to elude photographers by hiding behind a tarp held by her two assistants.

Until last week, it is believed Bullock was staying in her hometown of Austin, Texas.

James, 40, issued a public apology earlier this month to Bullock and his children after San Diego-based tattoo model Michelle "Bombshell" McGee claimed she had a months-long affair with him. Three more women — stripper Melissa Smith, photographer Brigitte Daguerre and an unnamed mistress represented by high-powered lawyer Gloria Allred — have also claimed affairs with James since the cheating scandal broke.

"Sandra is such a classy woman," a source tells RadarOnline. "To have her husband cheating on her and cheating with so many women, it's just something she doesn’t deserve.

"She's always conducted herself with dignity. A lot of people never understood her attraction to James but she was loyal to him. And not only did he cheat but he cheated with these women that just make you shake your head. Not that it matters anyway – the only thing that matters is he cheated."

Bullock and James married in 2005 at a ranch north of Santa Barbara.
