Hollywood actress Sandra Bullock has reportedly moved out of the house she shares with husband Jesse James following reports of his infidelity.

According to a source, the 45-year-old left the house Monday. Bullock, who won her first Oscar for 'The Blind Side', abruptly cancelled the London premiere of the film.

People.com reports that James has been accused of cheating on Bullock with a tattoo model.

Bullock and James met in 2004 during a tour of the set of the Discovery Channel's 'Monster Garage'. They married a year later in a sunset ceremony at a ranch north of Santa Barbara attended by 300 guests.
