Looks like Katy Perry's got the moves like Jagger. And on Jagger.
The singer tweeted a photo of herself with the Rolling Stones frontman after she sang with the rock icon during a Rolling Stones concert in Las Vegas.
After the concert, the sexy 28-year-old captioned the above image:
"Yes, I just gyrated on Mick Jagger. WHAT?! #Stones50."
"Mick & Kate forever!" she wrote the next day alongside another photo with the band. "Thanks for letting me be the 5th wheel last night! @Rollingstones"
Not one of the hottest Katy Perry pics we've seen, but a classic.
