She's got the moves like Jagger.
Katy Perry gave a surprise guest appearance at a Rolling Stones concert in Las Vegas on May 11.
The 28-year-old singer strutted onto the stage of the MGM Grand Garden Arena to sing a sultry duet with Mick Jagger, the lead singer of the legendary rock band.
The song, "Beast of Burden," had been chosen by fans through "social networks" before the performance, according to Jagger, who introduced the 1978 classic song to the audience.
The "I Kissed A Girl" singer, who appeared in thigh-high leather boots and a black leather dress, took to Twitter after the performance to divulge her enthusiasm.
"Mick & Kate forever!" Perry Tweeted, alongside a photo of herself with the 69-year-old legend. She later uploaded a snapshot of herself posing with the entire band. The caption read:"Thanks for letting me be the 5th wheel last night!"
The Rolling Stones are currently on their 50 & Counting tour, which will travel through cities across the United States and Canada. Their kickoff performance in Los Angeles featured a surprise performance from No Doubt's Gwen Stefani, followed by an appearance by Tom Waits at a show in Oakland.
