Christina Aguilera

We can rely on singer Christina Aguilera to give us advice on how to stay youthful through the years. Her ardent fans can attest to how her style evolved from her Mickey Mouse Club days to now that she is a coach in “The Voice” and boasts five Grammys.

Supporters can also turn to the “Genie In A Bottle” hitmaker when they are feeling conscious about their bodies. That’s because, in 2011, critics came for her following the release of this picture taken during a Michael Jackson tribute performance. But she responded with kindness, saying that she was confident with her body.
