Debi Mazar is an American actress best known for her starring role as Shauna on the comedy-drama television series Entourage, from 2004-2011.
Mazar appears in the films Return to Babylon, The Women and A Beautiful Life. A New York native, Mazar made her feature film debut in Martin Scorsese's Goodfellas as Ray Liotta's junkie mistress.
From that auspicious beginning, she went to work with such noted directors as Jodi Foster in her directorial debut Little Man Tate, Barry Levinson in Toys, Woody Allen in Bullets Over Broadway and Joel Schumacher in Batman Forever.
Mazar has also made her mark in the independent film world co-starring in such off-beat films as Nick Cassavetes' She's So Lovely and in Steve Buscemi's directorial debut Trees Lounge.
She was seen with Al Pacino in The Insider directed by Michael Mann and co-starred opposite Jackie Chan in The Tuxedo. Other film credits include a supporting role in Collateral, again for director Michael Mann and the Get Shorty sequel Be Cool.
She made her television debut on Civil Wars as Denise Iannello, a character who was then transplanted to another primetime show, LA Law.
Mazar developed and starred in her own sitcom Temporarily Yours for CBS and was a regular on the series That's Life with Ellen Burstyn.
