The artist sometimes known as Symbol Man publicly humiliated the partying heiress and her singing ability, according to the new issue of Us.

Paris Hilton was in the audience as Prince performed at Club 3121 at the Rio All-Suite Hotel & Casino in Las Vegas’s Club 3121 on April 20. At one point, Prince invited the “Stars Are Blind” crooner to join him onstage.

A “delighted” Hilton scampered onto the stage and the “Purple Rain” singer handed the wanna-be-pop star the microphone and told the audience, “Let’s see if she can really sing,” a source told the mag.

An angry and humiliated Hilton stormed offstage — and left the club two songs later, reports Us.

Hilton’s rep insists that the story is untrue, and Prince’s spokesman had no comment.
