Kelly Rowland's Birthday: Singer Turns 31, Style Evolution (PHOTOS)

As one of the original members of Destiny's Child, Kelly Rowland has been dressing like a superstar over the past 15 years. And with a bestie like Beyonce, it's no surprise she's is a style superstar.

Now a successful solo artist, Rowland has ditched the girl-group gear for high fashion and even higher hemlines (no use in hiding those gorgeous gams). Denim skirts and Uggs have given way to glamorous gowns and sensational sequin frocks.

The Grammy-nominated "Motivation" singer combines sex appeal with the kind of fashion risk-taking that gets you noticed. And we definitely notice.

To celebrate Rowland's 31st birthday today, here's a look at her awesome style evolution.
