Alec Baldwin and Fifty Shades producer Dana Brunetti engaged in a heated Twitter war on Wednesday, after Brunetti stated that the actor’s new memoir, Nevertheless, contains lies about a co-star’s age while they were filming the 2006 film Mini’s First Time.

Complete with name-calling, threats and insults, the two duked it out in a series of tweets because, according to Baldwin’s book, he says that he wasn’t aware that Nikki Reed — his stepdaughter in the film who his character was having an affair with — was underage until toward the end of the filming and “flipped out” because the producers had told him something different.

Brunetti called Baldwin out in an 11-tweet summary saying that Baldwin did know how old Reed was.

Baldwin then tweeted today, “And Hollywood producers like Brunetti never do anything shady or unethical?” The response ignited a very long back-and-forth, with Brunetti then replying, “Name something I’ve done shady or unethical, Alec. You lied, face it, admit it and move on. I’m not afraid of bullies like you.”

Baldwin tweeted back: “SAG rules require releases for scenes involving physical contact with minors. I take you have a copy of that?”
