Washington (ANI): British rocker Pete Doherty has splashed out 10,000 dollars on a portrait of ex girlfriend Kate Moss. The Babyshambles frontman was snapped buying the oil painting from artist Sam Shaker in London. Shaker was commissioned by Doherty to make the painting back in 2007 when he and the British supermodel were still together and very much in love, reports Contactmusic. However, he never paid the 600 dollars that Shaker charged for the painting titled 'Beauty' and the painter decided to put it on auction. That's when Doherty stepped in and decided to pay off the artist to claim the portrait.
