Lena Dunham stripped down to some underwear for a photo shoot for her new book, "Not That Kind of Girl: A Young Woman Tells You What She's Learned."
The "Girls" star posted a handful of photos to Instagram taken by photographer Autumn de Wilde with stylist Shirley Kurata. In two of the shots, Dunham poses in a pair of leopard print underwear and a cropped pink sweater. In another, she wears a coral sweater and briefs.
"It's always a mythic day with @shirleykurata (regram from @officialautumndewilde)," she wrote.
"Puppy Love- a cozy moment with @officialautumndewilde @rozbeauty @shirleykurata for #notthatkindofgirl author photo shoot," Dunham captioned the shot with her rescue dog, Lamby.
"Bc serious authors need serious photos..."
The 27-year-old actress was apparently posing for author shots for her upcoming advice book. Dunham shared the cover with fans in an Instagram post on Feb. 10 and revealed the book is slated for an October 2014 release.
Random House reportedly paid $3.7 million for the publishing rights, according to The Hollywood Reporter.
