Dunham: It's about me

Yes, Lena Dunham, the creative spark behind HBO's Girls, does reveal in her memoir Not That Kind of Girl that she was raped while a student at Oberlin College. But the guy's name wasn't really Barry. Dunham insists the name was a random pseudonym she used in the book. So Dunham writes on Buzzfeed, following reports that a real Barry she knew at college planned to sue her.

Dunham says her intention was never to go after the guy.

"Speaking out was never about exposing the man who assaulted me," she writes. "Rather, it was about exposing my shame, letting it dry out in the sun."

She also says she has no intention of pursuing legal or criminal action against the assailant.

For her part, Melissa on Wednesday spoke of her mom's courage at a "Women in Entertainment" confab in Los Angeles. "She was willing to say what others were thinking," Melissa said. "She thought of herself as a comic and had to be funnier than everyone else. She just wanted to do her job, and that was to make people laugh."
