Holy hot musical collaboration!!
As if The Rolling Stones weren't hot enough on their own, they upped the ante and set Las Vegas on fire when they brought Katy Perry out for a duet!
Yup, our little Katy Kat brought her booming voice and bangin' bod to Vegas to join The Stones for Beast of Burden.
And gurlfriend sooo gave legendary Mick Jagger a run for his money.
You KNOW she brought the sass!
