Gaga in Vegas for Britney's show
Lady Gaga has taken some time out from her busy schedule to catch pop pal Britney Spears' Las Vegas show.
The Applause singer was in the audience to see the Piece Of Me extravaganza at the Planet Hollywood Resort And Casino, where Britney has a residency.
I Wanna Go singer Britney had previously hinted that a celebrity would be dropping by, and before she performed she tweeted a message to Gaga, saying: "Come hang before the show starts. Can't wait to see you :)."
Gaga did go to see Britney backstage before the event and later tweeted a snap of the pair posing together, captioned: "Me and Brit Brit #Applause4Britney @britneyspears we had so much fun at your show!"
During the concert Gaga was spotted in a VIP section of the crowd. She left before the end, and the stars waved and blew kisses to each other while Britney, 32, carried on singing.
Gaga, 27, also dropped off a handful of roses at the end of the stage.
She later posted another message online saying: " Britney's dad gave us homemade BBQ, it was one of the best things I've ever eatin' in my LIFE."
