Lady Gaga's booty shaking was the best present her "Chicago Fire" boyfriend Taylor Kinney could get for her birthday.
After her performance at Roseland Ballroom in NYC on Friday, Gaga gave her fellow Aries boyfriend the best gift ever.
According to The New York Post , after Gaga and the actor entered the brand new BPM nightclub on West 42nd St separately, the singer "then assumed a stripper persona and put on a show for him. She was doing a serious lap dance and they started making out."
"He spanked her and she gave him a sexy lap dance. She was sneaking sme kisses backstage. They looked very happy and inseparable," said a partygoer about the celebrity couple, according to E! News .
Following the PDA, Gaga did a little catwalk and vogued for supporters on stage.
"It felt like you were seeing a private moment with her channeling all that sexual energy," the partygoer said. "She looked great."
Gaga later on went next door to THE OUT NYC where she had a private viewing of her gallery installation. She had about 200 fans waiting outside for her.
