In a display of star power no episode of Jersey Shore can match, Lady Gaga took in Britney Spears' Femme Fatale concert Saturday night in Atlantic City.
This wasn't lost on Spears, who announced it to the audience, saying, "I have a very special guest tonight... Lady Gaga is here." The place went bonkers.
Gaga, sitting up front in the floor section, stood and waved and a made a heart sign with her hands. Britney then hearted her right back. *Sniff*
Watch Britney announce the Mother Monster to the crowd:
Gaga, who was double-fisting drinks for much of the night, got on her feet and did a little fist-pumping during Britney's new single, "I Wanna Go."
Later, during a break in the concert, Gaga accidentally stole the show when the crowd started chanting her name and rushing over to snap pics.
Not that Britney minded sharing the spotlight one bit.
The pop star praised her #1 fan on Twitter later, writing "So amazing to have the beautiful @LadyGaga at the show in AC tonight. Love you girl."
