The ballad of Jesse James seems headed for a showdown, as family fallout continues amid infidelity allegations aimed at Oscar-winner Sandra Bullock's husband of five years.

In a fast-moving sequence of events, motorcycle customizer and reality-TV star James, 40, issued a hedged public apology to People magazine Thursday.

"The vast majority of the allegations reported are untrue and unfounded," the statement read. He declined to specify the ostensible minority of the information that was true, saying, "I will not dignify these private matters with any further public comment."

Tattoo model and San Diego stripper Michelle "Bombshell" McGee told In Touch Weekly on Wednesday that she and James began an 11-month affair while Bullock was shooting "The Blind Side," for which the star received a best actress Academy Award.

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

"This has caused my wife and kids pain and embarrassment beyond comprehension and I am extremely saddened to have brought this on them. I am truly very sorry for the grief I have caused them. I hope one day they can find it in their hearts to forgive me."

Citing an anonymous and undescribed source, reported that Bullock, 45, had left her and James' Southern California home days before McGee's claim surfaced. The image agency Flynet Pictures photographed James Thursday bringing his children to school alone, without Bullock. The "Monster Garage" host has three children - daughter Chandler and son Jesse Jr. with his first wife, Karla James; and a daughter, Sunny, with his second wife, adult-film star Janine Lindemulder.

Bullock has helped raise 5-year-old Sunny since at least December 2008, when Lindemulder was sentenced to 6 months in federal prison for tax evasion. And while there's no love lost between the two women, Lindemulder did tell "Good Morning America" last November that Bullock is an "excellent mother" who loves Sunny. Indeed, Bullock had written to the judge in Lindemulder's tax-evasion case saying, "I know the term 'stepmother' carries many connotations, one of them being a 'glorified babysitter.' My commitment and responsibility to Sunny, and Chandler and Jesse Jr., goes beyond that."

Which only makes the couple's split, if true and not temporary, all the more tragic.
