Back before she hit it big on 'Friends,' a 20-year-old Jennifer Aniston was best known to Howard Stern fans as a "NutriSystem success story."

The then-struggling actress appeared on Howard Stern's radio show in 1989 because she had recently lost weight on the program -- which sponsored Stern, Usmagazine.com reports. Sirius Radio, who houses Stern now, played the interview as part of 'The History of Howard Stern: Act III.'

In the clip, the shock jock flirted heavily with the would-be-superstar. "You're very lovely," he told her.
