The Voice

Simon Cowell thinks just because some singers are talentless, superstar wannabes not worthy to compete on "X-Factor" ... it does not mean they wouldn't be perfect for ... "The Voice." OH SNAP!

Sources who attended the Austin "X-Factor" auditions tell TMZ ... Simon and L.A. Reid came up with the brilliant idea to mess with the NBC show by convincing bad singers to audition for "The Voice" instead.

L.A. Reid was overheard on set telling one such wannabe, "If you decide to try out again, please do it on another show." To which Simon added, "Yes, the good news is I hear 'The Voice' auditions are happening next week."

Christina Aguilera has it out for Tony Lucca on "The Voice" because he spurned her while they worked on The Mickey Mouse Club -- this according to a former Mouseketeer.

Ex-Mouse Clubber Dale Godboldo -- who starred on the 90s MMC revival alongside Aguilera and Lucca -- tells TMZ, Tony was pretty popular in his Disney days ... "Britney was in love with him. Christina was in love with him. Mylin was in love with him."

But Christina and Tony never hit it off -- and Dale believes she's carried a grudge ever since, claiming, "All of this [Voice] madness was not brought on by Tony."

You'll recall ... Aguilera harshly criticized Tony's "Voice" performance Monday night -- calling the rendition of "99 Problems" "derogatory to women." The two have been butting heads all season.

Hell hath no fury like a Mouseketeer scorned.
