Spywitnesses spotted His Purpleness Prince dissing Her Herpesness Paris Hilton in Las Vegas on April 20th.

Paris was reportedly in the Vegas crowd at Club 3121 at the Rio All-Suite Hotel & Casino as Prince performed. He called to her, invited her on stage, of course she obliged, only to be handed a mic and commanded to sing, as Prince said cheekily to the audience: “Let’s see if she can really sing.”

An angry Paris stomped off the stage.
