(Cover) - EN Showbiz - Jesse James has been accused of being unfaithful to former fiance Kat Von D.

The on-again, off-again, couple are no longer together after the LA Ink star confirmed the news on her Facebook page over the weekend.

But RadarOnline are now reporting that the reason for the break up this time is because the motorcycle star cheated on Kat.

An unnamed woman claims to have been in a relationship with Jesse while he and Kat were "on a break" but also continued to see each other when they reconciled.

"You can't stay faithful because you hate yourself," she wrote on cheaterville.com. "Therefore you secretly hate everyone else in your life."

"That's why you treat women like s**t. Why don't you finally be a man and tell everyone why Kat dumped you this time?

"Is it because you lied to her and said that you didn't see anyone while you two were "on a break?"

"How did she find out about me Jesse? I know you didn't tell her, and I didn't say anything because I didn't even know that you two got back together until the entire world found out."

The scorned woman added that she was "no saint either" but that she had ended it with her husband before she started seeing Jesse.

"I'm disgusted with myself more than I am with you, I should have known better," she continued.

"Any man who spends every second on his phone texting is up to no good. Ironic how you spend so much time on your phone but won't return any of my texts or emails."

The woman claimed that Jesse had left her with a "parting gift" and that was the only reason why she was remaining anonymous.

A source close to Kat and Jesse told Radar that the couple were definitely over this time.

"They are done, through and through finished, split, game over," the insider said. (C) Cover Media
