In a newly-released excerpt from her upcoming memoir, "This Will Only Hurt A Little", the 39-year-old actress has opened up about her experiences with Franco, who has been dogged by claims of sexual misconduct in the past 18 months, revealing he once turned on her following a scene that required her to hit him in the chest.
"He grabbed both my arms and screamed in my face, 'DON'T EVER TOUCH ME AGAIN!' And he threw me to the ground. Flat on my back. Wind knocked out of me," she wrote, calling her former co-star a "f**king bully".
Busy reveals James apologised to her the following day, after the show's producers and director forced him to.
"This Will Only Hurt a Little", which hits stores on October 16, will also detail Busy's sexual assault at the age of 14.
She recently opened up about the incident after posting a photo of herself as a 14 year old online and explaining that's what she looked like when she was raped.
"This is me at 14," she wrote on Instagram. "The age I was raped. It's taken me 25 years to say those words. I wrote about it in my book. I finally told my parents and sister about it 4 months ago. Today is the day we are silent no more. All of us."
Busy did not reveal any other details about her alleged attack, but promoting the book on "The Ellen DeGeneres Show" last week (October 03), she broke down as she talked about her decision to come forward, first in the book and then on social media.
"It wasn't something that I felt like I was ever going to blast out on social media... It was hard. And really scary... I have a 10 year old, so when I look at that baby (in the photo she posted on social media), I see my kid. It's sadly the most unoriginal horror. I've struggled with it for so long."
