"It's official. Coming 10/7/14," was the tell-all caption accompanying Lena Dunham's Instagram picture of her holding her debut book, Not That Kind of Girl.
The tome, which The Hollywood Reporter bills as "frank and funny advice on everything from sex to eating to travelling to work", was sold to Random House in October 2012 for $3.7 million (£2.25m). Rather a tidy sum when you consider that only season one of Girls had aired at that point.
Thanks to gossipmonger Gawker, who published a leaked copy of the proposal two months after the deal was announced, we have a pretty good idea of the content. And it's every bit as Hannah Horvath - Dunham's obsessive writer protagonist in Girls - as you'd imagine.
Expect chapters such as Body, Red lipstick with a sunburn, How to dress for a business meeting and Other hard-earned fashion lessons from the size 10 who went to the Met Ball.
The cover, meanwhile, is a slick departure from the initial idea that was again leaked by eager press. Dunham has eschewed the dated concept with cupcake and Mary Jane illustrations in favour of a bold fuschia and black type face.
The writer and actress, who first attracted attention for her 2010 indie biopic Tiny Furniture, is currently enjoying critical acclaim for her third series of Girls, in which her character, who believes she is the voice of her generation, is also penning a memoir.
