Christina Aguilera has been a celebrity on some level for the better part of two decades now. She began as a performer on the Mickey Mouse Club when she was just 13 and by 2001 she was an absolute superstar.
With her powerhouse vocal stylings — on a par with great divas like Mariah Carey — Christina was already a dominant artist on the pop charts when her evolution into the hard-edged and smoking hot "Xtina" and accompanying song releases such as "Dirrty" culminated with her being named the Billboard Top Female Pop Act of 2003.
Over time Christina has shown a stunning ability to take pages from the books of other artists like Madonna and completely re-write them, forging her own charismatic and powerfully sexy presence.
As she's proven through her stint as a high-profile host on the hit TV vocal competition The Voice, she also knows how to stay dominant on the charts, with tracks topping Billboard charts as recently as 2016.
