The actress also reveals whether she's heard from him since speaking out.
For one, it's an incident she had already spoken about on "Watch What Happens Live" back in 2016. Also, she was trying to highlight a greater issue in the industry, not simply call out Franco for his behavior.
Appearing on "WWHL" again on Thursday night, host Andy Cohen asked whether she heard from Franco regarding her allegations after she initially made them in 2016 or after they blew up again in the press this month.
"The thing is about that, in particular, he and I, he had apologized to me, this was when we were 19," Busy explained. "No, not after I was on the show because we already talked about it. And that's why I was like fine putting it in my book."
"When I was writing the book, because I was talking about so many personal things, I always had in my head that things will get turned into clickbait. I naively did not think that would be one of them, because I talked about it on your show," she continued.
"When you read the book, in the context of the story and what I'm trying to get across, it really was one of those things that I was very surprised by last week, it really bummed me out, because I'm a woman in this industry who wrote a very personal book about my experiences in life and this industry and the headlines are all about a man," she added.
"I just was like, yeah that was my point the whole time," Philips continued, "so it really did bum me out."
She added that the two "don't have each other's information now," so she hasn't heard from him. Philipps also said he's "probably not thrilled" with the situation.
In her book, "This Will Only Hurt a Little," she accused Franco of throwing her to the ground on the set of "Freaks and Geeks" when they were teenagers. "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."
According to Philipps, Franco was forced to apologize to her. "It was barely a slap on the wrist," she wrote, "but that's how a boys' club works. I already knew there was no sense in trying to express ... how humiliating it had been on set. How James continually made me uncomfortable and got away with it because of his 'talent.'"
Philipps wrote that he did apologize the next day, calling him "gorgeous and charming as hell." She added, "These dudes so often get away with their shitty behavior because they smile at you and stare into your eyes and for a second you're totally transfixed and you just say, 'Yeah. It's okay. I get it ... I'm sorry I'm not a better actor. I'm sorry I'm not a prettier girl. I'm sorry.'"
