Busy Philipps is about to publish a memoir, one which details a shocking allegation about her one-time co-star James Franco.

An excerpt from the upcoming memoir, This Will Only Hurt a Little, has been obtained by Radar Online, and verified by Yahoo Entertainment, in which Philipps calls out her former “Freaks and Geeks” co-star for allegedly attacking her while filming a scene.

Philipps’ memoir describes Franco as a “f**king bully,” and details one incident that took place while they filmed a scene for the beloved cult hit.

As Philipps explains, she was directed to “gently hit” Franco in the chest while delivering her line, something that was not received well by the actor.

“He grabbed both my arms and screamed in my face, ‘DON’T EVER TOUCH ME AGAIN!’” she writes. “And he threw me to the ground. Flat on my back. Wind knocked out of me.”

Franco then stormed off, she continues, as the “horrified” crew rushed to help her as she lay on the ground.

Philipps later told co-star Linda Cardellini about what happened, and she advised Philipps to call her manager and report the incident.

According to Philipps, Franco apologized the next day but only because “he was ordered to do so by directors and producers”; she alleges he never received any formal reprimand for his actions.

Philipps’ allegation comes less than a year after Franco was accused of sexual misconduct by five women in an expose for the Los Angeles Times.

This Will Only Hurt a Little will be released on Oct. 16.
