SANDRA BULLOCK has moved out of the family home after claims her husband had an affair with a tattoo-covered model. The actress reportedly left the California house she shares with Jesse James on Monday - a week after winning her first Oscar. Sandra, 45, has cancelled a trip to London for the Tuesday's UK premiere of The Blind Side, for which she won the best actress award.

The actress said in a statement: "Due to unforeseen personal reasons, a trip abroad has been deemed impossible at this time." Bullock and James, the host of the Discovery Channel's Monster Garage reality programme, have been married for five years.

They have no children together but have fought a long legal battle for custody of James's daughter. Yesterday, more details emerged about his alleged mistress. Tattooed Michelle McGee - a porn model and ex-stripper - told a US magazine she and James, 40, started their affair last April.
