Mazar's feature film debut in Martin Scorsese's "Goodfellas" set the stage for an extensive career in both television and film. She has consistently worked with notable directors—including Oliver Stone, Spike Lee, Woody Allen, Michael Mann and Joel Schumacher—often portraying the sharp-tongued New Yorker in both dramas and comedy. Mazar's television credits include "Friends," "Ugly Betty" and her own sitcom, CBS' "Temporarily Yours". She presently stars as publicist Shauna on HBO's hit series "Entourage." Mazar also co-hosts "Under the Tuscan Gun," a successful internet show focused on Tuscan cuisine, with her husband. The couple have two young daughters and presently reside in both Los Angeles and Tuscany, Italy.
