Perhaps inspired by Damien Hirst's Sotheby's earnings, this weekend will see a first -- a self-portrait by Kate Moss goes up for auction. The 2005-2006 painting, entitled "Who Needs Blood When You've Got Lipstick," is drawn in, um, lipstick and bears the title inscribed in blood by then-boyfriend (and Babyshambles frontman) Pete Doherty. According to the auction website, the piece was "Bought directly from Pete Doherty's private collection and is accompanied by a receipt in his hand for the sale on a Soho House napkin." He's probably got a sweet markup, since it reportedly only cost him £15.
