Al Pacino brought a mystery blonde to producer Fisher Stevens birthday Tuesday at Pravda, says a spy. We’re told Pacino and his date joined a group including Liev Schreiber, Naomi Watts, Courtney Love, Matt Dillon, André Balazs and Gina Gershon for dinner and dessert. “Courtney kept trying to talk to Pacino, but he left early with his date,” says the witness. Stevens earlier attended a SnagFilm’s screening of his new doc “Beware of Mr. Baker,” about Cream drummer Ginger Baker at Crosby Street Hotel before heading to the club, where he was heard requesting Cream songs from DJ Todd Smolar. A rep for Pacino didn’t get back to us.
