Lady Gaga caught Britney Spears' Las Vegas extravaganza the other night and the internet is abuzz with word that Britney Spears and Lady Gaga met up in Las Vegas. Britney has hinted that she'd love to do a duet with the former Little Monster who now calls herself the Goddess of Love. So when Lady Gaga visited Las Vegas to see Britney Spears' Planet Hollywood residency show, there was anticipation in the air.

Lady Gaga is the latest pop stars to take in the Britney Spears show at  Planet Hollywood. Katy Perry and Miley Cyrus also took in the show. Gaga tweeted her entrance in advance.

Last week Britney hinted that Lady Gaga might be flying intweeting, "Little bird told me something cool today. See you soon @LadyGaga ;)."

Right before the show Britney Spears took to Twitter to tease "Tonight's show is gonna be a good one, I can feel it. Who's coming?"

Lady Gaga was seated in the VIP section with Britney's manager, Larry Rudolph and it looked like she was having a monster ball. Lady Gaga danced and sang along to all Britney's hits.

On her way out to beat the fan crush, Lady Gaga stopped to leave roses on the stage for Britney.

After the show, Lady Gaga posted a picture with Spears on her Little Monsters website saying "We had so much fun at your show! #Applause4Britney." And then she tweeted that "Britney's dad gave us homeade BBQ, it was one of the best things I've ever eatin' in my LIFE."

Britney Spears is in the middle of her two-year Las Vegas' Planet Hollywood Piece of Me residency.

Last December Spears told Saturday Night Online, "I would do a duet with Lady Gaga. I think that would be a lot of fun. I think she's very different and interesting and intricate."
