Compared to the hard-partying fictional superstar he played on TV for eight seasons (and has signed on to play in a film version), Adrian Grenier leads a pretty chill life as an actor/director/sometime musician. He was raised in Brooklyn by a single mom and attended the "Fame" high school before he started booking small parts in the late ‘90s. In 2002, he documented his search for his long-estranged father in "Shot In The Dark." His second feature-length documentary, Teenage Paparazzo, examined the complex relationship between the rich and famous and the media. In 2004, he converted to TV and took on the role he is best known for — Vincent Chase in HBO’s Hollywood-skewering comedy Entourage. Grenier, who plays piano, guitar and drums, has spent time jamming with various bands.
