Lena Dunham calls secrecy 'destructive'

Lena Dunham is no stranger to using her own life as fodder for her creative endeavours, most notably in her wildly successful HBO series Girls.

But the 28-year-old TV creator, actor and director can now add another accomplishment to her lengthy, and frequently candid, body of work:  She's now an author.

Dunham's highly anticipated new book Not That Kind of Girl: A Young Woman Tells You What She's "Learned" launched Tuesday in Canada. Like her hit television show, the collection of essays includes Dunham's outlook on what it's like to be young and female—including revelations of sexual assault, eating disorders and personal struggles with body image.

In a Canadian radio exclusive interview with Q host Jian Ghomeshi, the outspoken star described the moment she became an open book:

"Probably, like, the minute I started talking," said Dunham.

"I just never had a comfort with the idea of things that are supposed to be kept secret, and I think from an early age, I found the concept of secrecy kind of destructive."

Tune into The National Wednesday night on CBC-TV for more of Jian's interview with the plainspoken celebrity.
