On Sunday, May 12, at the MGM Grand Garden Arena in Las Vegas, Katy Perry joined the Rolling Stones onstage where she sang a duet with Mick Jagger on the classic Some Girls hit, "Beast of Burden."  Perry was ecstatic to have gyrated on Jagger and proudly tweeted about it on twitter.

So did Katy Perry have the moves like Jagger? She certainly did wearing a scantily clad ensemble including a black leather corset, matching thigh-high boots and a coordinating yellow and blue print skirt.

Perry, who tours the world performing in hundreds of arenas could not hide her excitement over being in the presence of Keith Richards, Charlie Watts, Ronnie Wood and singer Mick Jagger.

She tweeted 'Yes, I just did gyrated on Mick Jagger. WHAT?! #Stones50.'

She then posted a snapshot of herself on stage, with the caption: "Mick & Kate forever!"

Katy has become the latest celebrity guest to join the legendary rockers on stage as part of their 50 & Counting Tour. Katy followed the acts of Lady Gaga, Florence Welch, Gwen Stefani and ex-beau John Mayer who sang with the Rolling Stones in previous shows.  The next artist to move with Jagger will be Tom Waitts.

The guest spot came as little surprise over the weekend, as The Stones took to twitter to announce the news before the show. Perry herself replied to say she was "Much obliged and quite honored."

The band was also joined by a local school choir for the Las Vegas show, who performed "You Cant Always Get What You Want" with the group as part of the encore.

The MGM Grand will play host to another steller performance this Sunday, where artists such as Justin Bieber, Taylor Swift, Macklemore & Ryan Lewis, Jennifer Lopez, Lil Wayne, Christina Aguilera and more will grace the stage for the 2013 Billboard Music Awards.
