Now Gaga's appearance on a 2001 episode of "The Sopranos" has surfaced online, showing the world how 15-year-old Stefani Germanotta spent her time. In her cameo role, Gaga and her gal-pals help Tony Soprano's son A.J. get into some trouble at the school pool. All while trying to look sexy in a cropped sweater, smoking cigarettes and flirting with boys, of course.

In the season three episode, titled "The Telltale Moozadell," A.J. gets probation for the aquatic horseplay, and Gaga never shows up on the show again. We told you she was trouble -- the sort of trouble teenaged boys can't avoid.
