LADY GaGa is celebrating after landing her first Vogue magazine cover.

The Poker Face hitmaker — who’s known for her eccentric fashion sense — features in a fashion spread for the style bible’s March issue.

“They used to call me rabbit teeth in school,” GaGa tweeted on Saturday, along with a picture of her upcoming Vogue cover. “And now I’m a real live VOGUE BEAUTY QUEEN!”

Meanwhile, GaGa has reportedly been fighting with boyfriend Luc Carl.

“GaGa and Luc are fighting a lot,” a source told America’s Life & Style magazine.

“Their relationship has never been perfect — it’s always been tumultuous — but now it’s hanging by a thread.

“When she and Luc were catching up with her old pals in New York over New Year’s, he made zero effort to get to know them.

“He sat in the corner at the bar and pretended like no one else was there. Meanwhile, she was so happy to see everyone and catch up.

“Her friends think he’s using her because of how famous she is. He doesn’t treat her very well.”
