Alicia Keys

Born in Harlem, Keys was reportedly tagged as a musical genius from the age of five, and attended Manhattan's Professional Performance Arts School. She graduated from high school early, at age 16, but a brief stint at Columbia University left her dissatisfied, and she soon hearkened off to greener pastures, offered a prestigious record contract by Davis.

In terms of acting roles, it may surprise fans to discover that Keys' on-camera appearances date back to the age of five, when she appeared as a guest star on a 1985 episode of The Cosby Show. In the early years of the diva's music stardom, her filmed work, of course, consisted almost exclusively of performance footage, such as her 2001 appearance on Saturday Night Live and the concert films America: A Tribute to Heroes (2001) and Shelter from the Storm: A Concert for the Gulf Coast (2005) -- both reflecting Keys' interest in humanitarian causes. In time, however, the superstar branched out into dramatic efforts, with small roles in such A-list features as Glory Road (2006), Smokin' Aces (2007), and The Nanny Diaries (2007). ~ Nathan Southern, All Movie Guide
