Jesse James is NOT the bad guy… at least according to him.

The motorcycle enthusiast swears up and down he never did or would cheat on his ex-porn star wife, Bonnie Rotten.

James took to Instagram this weekend to apologize and admit to some wrongdoings.

He wrote in a lengthy since-deleted IG caption, “Baby I didn’t cheat on you I swear!! I’m sorry we got into a fight.”

“I’m sorry I called you a ‘retard’ when we were fighting.”

His apology post comes after Rotten exposed him on Instagram for cheating on her while she’s pregnant.

James doesn’t have the best track record when it comes to staying faithful to his female companions and partners.

“I’ve never tried to cheat on you. I’ve never had the urge to cheat on you. You are the only one I want, forever.”

The former “Monster Garage” host explained how he was such “a man” that he denied advances from other women.
