AceShowbiz - The tattooed porn star who sparked the beginning of the end of Sandra Bullock's marriage has offered the actress a "heartfelt apology" for all the heartache her revelations have caused. The Oscar winner walked out on husband Jesse James last month as Michelle McGee went public with claims of an 11-month affair with the TV mechanic.

Two other women have since come forward with similar claims, while a fourth mistress is also alleged to have been involved with James while he was married to the actress. Now, as reports suggest Bullock is on the verge of filing for divorce, McGee has issued a public apology to the star, admitting she "feels bad" for her one-time love rival.

When asked what she'd say to Bullock if the two women were ever to meet, McGee told Australian TV show TodayTonight, "I'm sorry for your embarrassment. I'm sorry all this is public. I'm sorry for everything." McGee then added, "She (Bullock) must be hurt, devastated, upset, embarrassed. I want to give her a heartfelt apology. I'm sorry for her embarrassment and pain. I do feel really bad about it."

But McGee's apology is unlikely to win Bullock over - the model insists she understands what the actress is "going through" because she was "duped" by James too when he led her to believe his marriage was over. She adds, "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."
