Rihanna

At just 20 years old, Rihanna doesn't have any plans on stopping her successful career. She was introduced to the music industry when she was just 15, and it's been nonstop since then! She released her first album, Music Of The Sun in 2005, and she's already up to album #3. So what's our fave pop star up to these days? She just wrapped the Glow in the Dark Tour. But has no plans on taking it easy. People reported that Rihanna is working on her own fashion line. And she also has her own charity, The Believe Foundation. Seeing as how she just re-released Good Girl Gone Bad with additional tracks, she's not jetting off to a vacay any time soon.
