Can't always get what you want…but Katy Perry sure did at the Rolling Stones concert in Las Vegas Saturday night!
Yep, the 28-year-old pop star hopped on stage with Mick Jagger & Co. for a duet of "Beast of Burden."
Wearing thigh-high boots, a white skirt and a black bustier, Perry looked right at home performing with Jagger, Keith Richards, Charlie Watts and Ronnie Wood.
She was obviously excited by the gig, tweeting afterward, "Yes, I just did gyrated on Mick Jagger. WHAT?! #Stones50." (Before you grammar snobs launch into an attack, she quickly responded to a tweeter who slammed her for her "appalling" linguistics, writing, "I noticed that. I guess I was too excited. Sorry mom.")
She also tweeted a pic of herself and Mr. Jagger, writing, "Mick & Kate forever!"
"Thanks for letting me be the 5th wheel last night! @Rollingstones," she added, posting a smiley shot of herself and the guys.
Clearly it was a teenage twentysomething dream come true!
