GET OUT! LADY GAGA WAS ON SOPRANOS WHEN SHE WAS FIFTEEN! SHE KINDA LOOKS LIKE CHELSEA CLINTON!

Lady Gaga wanted fame and fortune so badly that she briefly joined the mob in 2001.

A new clip has surfaced from season three of the "Sopranos" -- entitled "The Telltale Moozadell" -- in which a 15-year-old Gaga plays a small role as one of A.J.'s (Robert Iler) mischievous classmates.

Tony Sopranos' good-for-nothing son is seen racing his friends in the school pool as the "Paparazzi" singer, clad all in black with dark hair, and three of her friends hang out nearby and smoke cigarettes.

"Did you girls see me out there?" A.J. asks the group.

"Yeah, it looked like you were cheating," Gaga says coyly.

Spurred on by the guys, who throw a teacher's desk into the water, one of Gaga's pals starts throwing sports trophies and other equipment into the pool as the singer simply laughs from the bleachers.

While A.J. gets probation, the soon-to-be pop phenomenon is never seen again.

But this is not the 24-year-old New Yorker's only small screen gig.

Four years after she appeared on the HBO mob show, she turned up on MTV's "Boiling Points," in which a hidden camera films unsuspecting New Yorkers as actors egg them on to react. Winners can take home $100 but Gaga was unable to stay mum about being served a dirty salad.

"This is disgusting!" she tells the waitress. "Who puts that in their mouth? Would you put that in your mouth? There's s--- all over it!"

In 2008, on the brink of fame, Gaga showed up on "The Hills" in a rubber jumpsuit with a broken zipper. The brunette songstress stole the scene fro, Whitney Port and Lauren Conrad, who were forced to fix the zip.
