Jesse James' children are reportedly living with Sandra Bullock.

The 'Blind Side' actress is said to have taken on the care of Sunny, six, Chandler, 15, and 12-year-old Jesse Jr. - the motorcycle entrepreneur's children from previous relationships - while her estranged spouse is in rehab being treated for sex addiction.

However, she is not believed to be staying at her Hollywood home with them.

A source told website TMZ: "It's a positive sign about Sandra's relationship with Jesse."

Despite speculation the couple are set to divorce following allegations Jesse cheated on Sandra with at least four other women, it has been claimed the 'Monster Garage' host had reassured his 45-year-old spouse he would never deny her access to his children.

A source said: "Jesse told Sandra he's going to make sure she sees Sunny as often as she'd like when he has her. She's spoken to her and the other kids and has said she's not going to lose them."

However, the 45-year-old actress has no plans to bid for legal custody of the children if she does file for divorce.

Her representative said: "There have never been any plans for Sandra to adopt any of Jesse's children."
