Jesse James' former mistress has apologised to Sandra Bullock for ruining her marriage.

Tattoo model Michelle 'Bombshell' McGee - who claims to have had an 11-month affair with the motorcycle entrepreneur - wants to show the Oscar-winning actress how sorry she is for her actions but is adamant Jesse is the one who should take most of the blame.

She said: "Sandra, I'm sorry for your embarrassment. I'm sorry all this is public. I'm sorry for everything.

"I feel bad for Sandra. I want to give her a heartfelt apology."

Michelle claims Jesse - who is currently in rehab receiving treatment for sex addiction - duped her by saying he and Sandra were separated.

She told Australian TV show 'Today Tonight': "I feel like I was duped just as much as Sandra was. I feel like I was lied to just as much as she was. If Jesse was upfront with me in the beginning, we wouldn't be in this situation."

Since Michelle's revelations Sandra has fled the family home and is now living in a rented property in an exclusive Los Angeles neighbourhood.

Jesse's three children from previous relationships - Chandler, 15, 12-year-old Jesse Jr. and Sunny, six - are currently staying with her, and friends say this has lifted her spirits.

One pal told X17Online: "She is really happy right now. The kids have really made her feel good. She's thrilled that she has impacted their lives. Sandra is much better and stronger than she was a couple of weeks ago. When this thing dies down Sandra will emerge stronger than ever."

However, the 45-year-old screen beauty is still said to be determined to divorce Jesse - who has been accused of having other affairs - once he leaves rehab.

The friend added: "When Jesse's out of rehab, the divorce will speed up."
