Lena Dunham just pulled her version of a Beyoncé.

The Girls star released a new book, Is It Evil Not to Be Sure?, on Tuesday without any warning, dropping the limited-edition text -- containing excerpts from a "most absurd & secret" journal she kept as a 19-year-old -- via an Instagram post.

If you managed to score one of the 2,000 signed copies, you might get even more perks. "Your copy may even have a very exclusive pen smudge..." Dunham joked on Instagram.

The best news? It's for charity, with profits benefiting the writing program, Girls Write Now.

The 30-year-old creator also got a jump start on juicy revelations by partaking in a Q&A on Khloé Kardashian's app. (It's only fair, seeing as the reality star wrote an op-ed about faith and her marriage to Lamar Odom for Lenny Letter.)

Dunham opened up about her workout regimen, admitting exercise has never been her "strong suit" and revealing she goes "in and out of routines."

"I've always been physically lazy since I was a baby and never even crawled, just rolled!" she explained. "My favorite form of exercise I've found is Tracy Anderson Method, because it's all about finding your strength and enjoying music. And I love to dance so much -- I consider myself a (privately) very brilliant dancer."

She also said she is currently trying to grow out her hair -- "I constantly wish I could throw it back into a ponytail or experiment with braids and waves." -- and declared which celebrities she gets a "lady b*ner" for.

"I think Tom Hardy is so handsome that it's almost too much. It's rude. I wish he would tone it the f**k down," Dunham joked. "And Lupita Nyong’o will tell you I'm basically her stalker and she'd be right to take out a restraining order on me. That being said, my man is the cutest of them all."

The Kardashian-Dunham collabos are a long time coming. The Girls genius previously defended Khloé and her sisters as "awesome entrepreneurs who are all about sisterhood." Hear what she had to say in the video below.
