Watch your back, Britney Jean Spears, your former pop nemesis is ready for round two - and she's been working out.
While Britney's been busy promoting her new single, her Vegas residency and flaunting her tres hot gym-honed body, it seems that her fellow Mickey Mouse club compadre Christina Aguilera has also been getting in shape.
Appearing on The Tonight Show With Jay Leno to promote the fifth season of The Voice in the US, the 32-year-old looked AMAZING in a figure-hugging black mini.
While Christina might have struggled with her weight over the years, it looks like her fitness and healthy eating regime has more than paid off this time. What a transformation!
As well as discussing her love life and family, Christina also told Mr Leno: "'At this point of my life, I'm 32 and I feel sexier than ever because you know what you want."
Sure as heck looks like it.
See Christina through the years in our gallery. Girl done good.
