Alleged cheat Jesse James appears to be admitting(almost)he’s been a bad boy.

As the rumors fly he’s been having it away with a tattooed mistress, the 40-year-old biker insisted today: ”The vast majority of the allegations reported are untrue and unfounded.”

OK, we get that.

But then he goes on: ”Beyond that, I will not dignify these private matters with any further public comment. 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.”

So were they having sex…or was it just a text affair.

We bet Sandra doesn’t care and she’ll be outa that marriage faster than one of Jesse’s choppers!
