Pop princess Katy Perry "gyrated" on Sir Mick Jagger while performing on stage with The Rolling Stones last night (May 11).

The stunning songstress joined the legendary band during a show for their '50 & Counting' anniversary tour at Las Vegas venue MGM Grand.

Perry was the group's special guest at the gig, and joined them on stage to perform a rendition of 'Beast of Burden'.

Perry took to Twitter after her stage appearance to gush about the guest slot, writing: " Yes, I just did gyrated on Mick Jagger. WHAT?! #Stones50 (sic)."

When a fan criticised her "appalling grammar" in the sentence, Perry fired back with a funny apology.

She added: "I noticed that. I guess I was too excited.  Sorry mom (sic)."

Perry follows in the footsteps of a range of stars who have joined Jagger and co. for their stage comeback, including No Doubt singer Gwen Stefani and country star Keith Urban.
