Hold onto your hats, Sopranos fans -- you're about to meet a new character.

Tony (James Gandolfini) will meet up with a young "party girl" on the Nov. 3 episode of The Sopranos, People magazine's "Insider" column will report tomorrow. 

The mystery woman is played by Leslie Bega, who starred as grade-obsessed student Maria Borges on ABC's popular series Head of the Class, which aired from 1986-91. 

According to People, Gandolfini sent Bega two dozen roses "to break the ice" before their first scene together. 

Bega is no stranger to TV roles. Her time on Head of the Class was highlighted by a 1988 visit to Russia -- the first time a prime-time series had journeyed to the Soviet Union to film an episode. 

The Sopranos is going great guns in its fourth season. Its season premiere last month was the most-watched show in HBO's 30-year history. (13 million of them tuned in). 

The show took an 18-month hiatus from the end of its third season to last month's premiere -- leaving its fans hungry for more episodes. Series creator David Chase has said that he expects next season to be the show's last. 

However, there's recently been talk of perhaps extending The Sopranos another season and/or turning it into a big-screen movie. 

The mobsters-on-Prozac series has been a huge boon for the show airing after it -- Larry David's Curb Your Enthusiasm, which has been earning some of its best numbers in its 10 p.m. time slot. 

HBO will air a documentary called Cathouse after The Sopranos season finale in December.
