Christina Aguilera

Considered one of the most legendary singers of her generation, Christina Aguilera started as a “Mickey Mouse Club” member. She, however, broke into the scene as a sultry and lean pop princess in the early ’00s with solo bangers such as “Come On Over Baby (All I Want Is You)” and “Genie in a Bottle.”

Apart from her well-known powerful voice, Aguilera also prides herself on her out-of-this-world appearances, which have become her brand. She’s been known for her excellent shape, although she struggled with body image after having her son. She continued touring and hit the fitness center, losing 50 pounds along the way.
