Band Or Solo Artist?: Solo

It's not uncommon for a songwriter to hone their skills before making the leap to popstar status as a singer. Our former cover girl found success as a songwriter for the likes of Britney Spears and Mary J. Blige, all while enrolled at Emory University in Atlanta. By 2006, she inked a deal with Timbaland's record label and It didn't take long for the two to come out with a hit record. With "The Way I Are" topping the charts in 2007, Hilson earned two Grammy nominations and a certified gold debut album.
