Wild child! Lady Gaga as a rebellious 15-year-old on hit TV show The Sopranos

We're used to seeing Lady Gaga in a variety of crazy and controversial styles.
But the 24-year-old star was once just a regular teenager like anybody else with normal, down to earth looks.
Gaga, real name Stefani Germanotta, had a guest spot on hit show The Sopranos when she was 15 years old.

And it's clear the young brunette was already eager for the spotlight.
In the episode, called The Telltale Moozadell, she appears in a pool scene in which Tony Soprano’s son A. J. and his friends are swimming at their high school pool after hours.
Gaga plays one of three friends who watch and laugh as the boys swim.

When the boys start to get out of hand and do some vandalising, one of the girls joins in while Gaga and the other girl look on and laugh.
And the teenager was already flirting with risque roles as she wore a midriff-baring top and smoked a cigarette.
It looks like Gaga started as she meant to continue, judging by her very cheeky costume on stage earlier this week for the We Are Plastic Ono Band concert held at LA’s Orpheum Theatre.

The Just Dance star recently took to the stage with John Lennon's widow Yoko Ono.
And she completely upstaged the 77-year-old as she teetered around the stage in a pair of super-high platform boots.
Her typically cheeky outfit - a bejewelled catsuit - deliberately exposed her bottom.
Gaga joined with the Plastic Ono Band, formerly a loose supergroup of musicians that Lennon assembled 40 years ago.

But Ono was not at all fazed by the eccentric pop star, focusing instead on how happy she was to be performing again.

She said: 'I have never done a show in L.A., so I am very happy to be finally doing it.'
The Alejandro singer and Ono performed in front of a sold-out audience.

Gaga tweeted: 'WE ARE PLASTIC ONO. I got to sit in as a guest musician tonight, what a legendary band + mother, Yoko.'
Earlier in the day the 24-year-old boasted about her musical success, as she tweeted: 'Today THE FAME spends its 100th consecutive week on Billboard.
'I wrote it myself + sang it live everynight. Thanku for believing lilmonsters.'
