Jeff Archuleta

David Archuleta’s psycho stage dad Jeff Archuleta has been banned from being backstage and behind the scenes at American Idol.

Here’s how it went down. “Idol” sources tell TMZ Jeff has been a complete pain in the ass, interfering with the entire production. He has badgered producers, the band, vocal coaches and even other contestants. The final straw came this week, when Jeff wanted to change the lyrics to David’s first song, “Stand By Me.” Jeff insisted on adding a verse from Sean Kingston’s hit, “Beautiful Girls.” Producers sent him an e-mail telling him the lyrics could not be changed. They were beyond pissed when David sang the song with Kingston’s lyrics during the live show.

We’re told by changing the lyrics, it created problems with the song’s publisher and cost “A.I.” a lot of money.

Congrats to Idol for banning this punk dad.  If anything is going to derail David and send him into a $1,000/day coke habit then it is likely his over possessive daddy.
