The US superstar invited the eager supporter backstage after she flashed her at a concert.
And the frisky star swiftly dived in to ‘grope’ the fan’s body and ‘tweak’ her nipples, before adding her personalised artwork – GA GA – on each boob.
The thrilled fan, 22-year-old Jana Babez, posted the picture on Lady Gaga’s Little Monsters fan site.
She said: “Gaga picked me out from the audience calling me a “pink princess”.
“I jumped over the railings losing a shoe along the way (thankfully the security guard handed it back to me).
“When I saw Gaga I flashed my boobs at her, and at 55,000 audience members.
“She grabbed my boobs and then looked at me shocked and asked ‘wait how old are you!?’ When

“Afterwards she looked at her masterwork and said ‘Please don”t get that tattooed, I know it’s my name but’s it’s really ugly’.
“She wrote GA on the one boob and GA on the other. LIFE MAD.”

The singer randomly called Charlie up and asked if she could perform the raunchy striptease on him with Britney Spears for her first ever ‘X-rated video’.
But he is still waiting and said: “We didn’t share any scenes but I actually spoke to her on the phone.
“She wanted me to do a music video with her that was going to be the first X-rated video.
“It’s her going to this strip club, with Britney Spears or somebody, and they’re dancers and I’m
“And she wanted to do a full striptease as a lap dance for me, and she told me, ‘If there’s one person that should receive this X-rated lap dance, it’s you.’ I was so flattered, but we never spoke again.”
