Sandra Bullock to end her marriage - report

Sandra Bullock has allegedly decided to divorce Jesse James.

The Oscar-winning actress - who has been left devastated by claims the motorcycle enthusiast cheated on her with at least four other women - has already taken steps towards ending their almost five-year marriage after realising she could never forgive him.

A source told RadarOnline.com: "She's had enough. She's ending the marriage."

Although she wants to end their union, Sandra has no plans to gain custody of any of James' three children from his two previous marriages.

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

The news comes just days after Sandra - who left the marital home after the first revelations regarding Jesse's 11-month fling with tattoo model Michelle 'Bombshell' McGee surfaced - told friends there is no chance of saving her marriage as she could never trust him again.

One pal told People.com: "Sandy has decided there's no way their relationship can be fixed. Once the trust is gone, there's nothing left."

James - who is also accused of sleeping with stripper Melissa Smith, photographer Brigitte Daguerre and an unnamed mistress who is represented by high-powered lawyer Gloria Allred - has spoken about his regret over the upset and hurt he has caused Bullock.

He said: "There is only one person to blame for this whole situation, and that is me. It's because of my poor judgement that I deserve everything bad that is coming my way."
