Lily Allen wore a cute blue Little Bo Peep costume at the G-A-Y performance in London. Allen accessorized her stage costume with pink nails and lipstick. Allen showed off her pert bottom in racy underwear. She proved her critics wrong by revealing her slim and beautiful figure. Allen sang Alright, Still and other popular tracks from her new album, ”Its Not Me, Its You.” After her concert, Allen went partying at Bungalow 8, still attired in her bum baring costume.
