Grammy Awards 2009

NOMINATION: Best Pop Collaboration With Vocals for "No Air" with Chris Brown

HER STYLE: The American Idol winner takes a youthful approach to fashion, often choosing bright colors, bold prints and metallics by designers like Dolce & Gabbana and Betsey Johnson.

OUR PICK: This waist-cinching Zac Posen design would flatter Sparks's figure while adding a little edge to her usual girly look.
