Lady Gaga Attends Britney Spears' Las Vegas Show

Lady Gaga popped up at Britney Spears' Planet Hollywood gig in Las Vegas earlier this week. Spears is currently in the midst of her Pieces of Me residency at the venue.

"Tonight's show is gonna be a good one, I can feel it. Who's coming?" Brit wrote to her followers on Twitter before the gig.

In response, Gaga said she'd be donning her "long blond hair" and "androgynous wear" for the two-hour concert. Spears replied: "Come hang before the show starts. Can't wait to see you."

During the show, Gaga was spotted dancing along with Brit's music from the VIP section. After the show, the pair posed for pictures backstage:

"Me and Brit Brit <3 #Applause4Britney @britneyspears we had so much fun at your show!" tweeted the Mother Monster.
