Michael Jackson has reportedly shut down his private life in an attempt to record a successful comeback album.

The faded singer has set himself up in Las Vegas to record his new LP, but has apparently cut off contact with those around him to concentrate on the project.

A source tells PageSix, "He's not going to be involved in any personal relationships with women until he gets this record done. He's dumped the nanny - she's not around any more.

"Michael is producing the album himself and has banned his kids from the recording studio. He realises this is very important and doesn't want any distractions.”
