The Artist: Christina Aguilera
Her Original Image: Much like Britney, Aguilera looked and felt like the girl next door when she released her self-titled debut album in 1999. Songs like "Genie in a Bottle" and "What a Girl Wants" were PG-13 at best.
How She Changed It: After releasing a Spanish album and a Christmas album, Aguilera returned in 2002 with Stripped, a much more mature effort from her. She took on the role of her alter ego "Xtina" on the album and released a single called "Dirrty" that completely changed the way people looked at her.
