Pop bad girl Christina Aguilera has been the dirrty mistress of many a teenage dream. Born on Staten Island, New York, on 18 December 1980, sexy Xtina has been singing ever since she was a child and known as 'the little girl with the big voice'. Her big break came in 1993 when she joined the Disney Channel's variety show The New Mickey Mouse Club. Britney Spears and Justin Timberlake were co-stars. She was initially marketed as a bubblegum teen pop artist, but didn't like the image and turned herself in to the bad girl of teen pop instead with the launch of Dirrty and Stripped. Her more sexually provocative image came with photoshoots often featuring her nude or semi-nude. She famously kissed Madonna on stage and has been quoted as saying: "I find it hornier looking at women than men. Sorry, I love experimenting with my sexuality. If that means girls, then so be it."
