She insists she's not to blame!

Ben Affleck's Playboy model hookup Shauna Sexton swears she's not responsible for him falling off the wagon and going back to rehab, and she's defending herself against the accusations on Instagram.

“Never drank around or with him for the record,” she wrote in the comments section of a photo of herself drinking red wine, after a fan said she got the Oscar winner "thrown in rehab."

When another commenter pointed out that she had been "arrested twice for underage drinking and public intoxication just last year," she didn't have anything to hide.

"I love to drink and party! Absolutely dude. Most 22 year olds do," she fired back before clarifying exactly what happened.

"I made a dumb mistake and an embarrassing one at that. Do these mistakes mean I would disrespect someone’s hard-earned sobriety by drinking with them or in front of them? Hell no. I have limitless respect for those who take action and actually do something about it. With that being said, Ben is a grown ass man, baby. He makes his own decisions. Blaming a 22-year-old for someone’s 3rd time in rehab is just ridiculous. He is human. I am human,” she added.

Her fifteen minutes of fame is officially up!

Happy as shit man
