Pop superstar Madonna has sparked reports of a facelift after she was photographed leaving a New York medical building with two black eyes. The Hung Up hitmaker, 49, tried to cover up apparent evidence of cosmetic surgery by donning a pair of dark sunglasses, but the dark circles around her eyes were still clearly visible. The singer has never publicly admitted to going under the knife, crediting her toned physique to yoga and a vigorous exercise regime.
