If she scores this jaw-dropping book deal, Lena Dunham won't be just one of the "Girls" anymore.

Bidding for Dunham's upcoming book skyrocketed to $3.6 million on Wednesday, according to Deadline.com's Mike Fleming. Fleming reports that this number could climb even higher:

The numbers for the book of advice and anecdotes from the 26-year old creator of the HBO series Girls should go even higher as publishers see her as an influential creative voice for young women. She met yesterday with editors. Stay tuned.

Dunham's literary agent Kim Witherspoon of InkWell Management is working on the deal, which should be finalized soon, according to Deadline.com. Witherspoon is an ideal agent to contend for Dunham's deal, as she herself founded an agency at 26 years old and now represents the likes of Sophie Kinsella, Lionel Shriver and Anthony Bourdain, the New York Observer notes.

Slate's David Haglund reported on Monday that Dunham's book deal had a set an "in-house floor of $1 Million” for U.S. rights to the book. Dunham told the online magazine: “There is nothing gutsier to me than a person announcing that their story is one that deserves to be told, especially if that person is a woman.”

Dunham's book, tentatively titled "Not That Kind of Girl: Advice by Lena Dunham," is a collection of essays with an advice motif.

"In the intro, Dunham is self-deprecating about the idea that she has any wisdom to share, but says that if the book can help anyone avoid some of the mistakes she’s made it will be worth it," according to Slate. The proposal says the work will include candid accounts of "losing her virginity, trying to eat well (detailed diet journal included), obsessing about death, and so on, along with tips about how to stay focused on work, how not to ruin a potential relationship, and what have you."

Dunham's potential multi-million dollar deal is certainly impressive addition to her list of accomplishments. The 26-year-old filmmaker and actress has written for The New Yorker and Rookie. Her feature-length film "Tiny Furniture" won Best Narrative Feature at the 2010 South by Southwest festival.
