The Stones announced the news of Perry's appearance Saturday on Twitter a few hours before the show. "I'm much obliged & quite honored!" Perry tweeted in reply. After her appearance, the obviously excited singer again took to twitter, writing: "Yes, I just did gyrated on Mick Jagger. WHAT?! #Stones50"
