In the late 1990s pop superstar Christina Aguilera was in hot competition with Britney Spears, but it seems like Christina has come out on top in that race. She’s remained popular since those days, which isn’t easy to do in the music biz, and has been involved in several philanthropic endeavors including the fight against AIDS, the importance of voting, and an attempt to end world hunger.

Despite her do-good efforts, Christina’s often criticized for her raunchy on-stage costumes. Rumor has it that her own grandmother was once disappointed to see Christina wearing so little in one of her music videos. The 2010 video for the single Not Myself Tonight features Christina transforming into several different characters, one of whom is wearing a pair of sunglasses from the Carrera vintage collection.
