On Saturday, Amy Schumer tweeted a picture of her first book, The Girl With The Lower Back Tattoo, due to be released on August 16. Surprise! She's naked on the cover.

The 34-year-old is no stranger to being naked in pictures. She was photographed naked last year by Annie Leibovitz for the famous Pirelli calendar. She also tweeted a picture of herself topless in response to movie critic/total jerk Jeffrey Wells, who, in a review of her movie Trainwreck, described Schumer as "Jennifer Aniston’s somewhat heavier, not-as-lucky sister who watches a lot of TV and should probably work out more."
