The somewhat surprising breakup of Jesse James and Kat Von D was sparked by a blowout fight over another woman, according to Radar Online.
According to an eyewitness, Jesse and Kat had an argument outside of her L.A. home Monday about another woman before Kat told him to leave.
“They were outside and I could hear them fighting. Kat kept throwing some woman’s name out and saying she didn’t like him living so far away.”
“Jesse finally said, ‘Fine, f**k you!’ and sped away on his bike," the source said. "Kat sat in her Bentley with her head on the steering wheel.”
“It was clear from the tone of the conversation that Kat Von D was accusing Jesse of something with this other woman,” the eyewitness said.
“So it didn’t surprise me when I heard they’d broken up.”
For the record, this is not confirmed, so assuming Jesse cheated on Kat - while understandable - is probably premature without more details.
