Is the commercial audition in knoxville, tennessee on june 4th real?

My sisters friend was telling her about auditions she heard on the radio. That the announcer asked if your kids want to be on disney. That there is going to be an audition in knoxville, tennessee on June 4th. I tried looking for it and all I could find was "The Events" which has an ad about knoxville and you can sign up. It was disney supported. But, I want to know if this is a scam because I'm leading it to being one.
