Debi Mazar (born August 15, 1964) is an actress known for her trademark Jersey Girl-type appearances, and as edgy, sharp-tongued women in independent films. She began her career as a hip hop b-girl in New York City in the 1980s and befriended a pre-fame Madonna.

Her first television appearance was on the pilot for a hip hop telelvision dance show, Graffiti Rock in 1984.

She also appeared in three Madonna videos - "True Blue", "Papa Don't Preach" and in "Music".

Mazar has played a number of minor-yet-colorful supporting roles in a variety of movies, including: as Sandy, Henry Hill's girl on the side in GoodFellas (1990), The Doors, Bullets Over Broadway, and as Spice (of Sugar and Spice) in Batman Forever (1995).

She had a recurring role in the 1993-94 season of the TV drama L.A. Law.

She has appeared in independent films like Inside Monkey Zetterland and Nowhere but has also dabbled in mainstream attempts like Batman and her short-lived sitcom "Temporarily Yours." (The sitcom was about a woman who, in an attempt to get a good apartment in New York, lies about being employed with a temp agency and then shows up at the agency begging for work.) From 2000–2002 she played "Jackie" on the television drama That's Life.

Currently, she is in a supporting actor role on Entourage, an original comedy series on HBO.

Mazar's father, Harry Mazar, was born in Latvia to a Jewish family, her mother, Nancy Kappes, is of Italian Catholic descent.

She also appeared as the genie in the Space Monkey's video, "Sugarcane".
