OK, I’m not sure how true this rumor is, but PageSix.com is reporting that Pat O’Brien will no longer continue his job on The Insider following his rehab treatment.

Instead, a source tells PageSix.com that Pat O’Brien will be dropped from The Insider and temporary replacement Donny Osmond will take over.

Pat O’Brien is currently undergoing rehab treatment that he started on February 8 to “maintain his sobriety.”

A rep for The Insider would not confirm the Donny Osmond replacement rumors, saying, “Pat O’Brien is focused on his recovery in rehab, and it’s inappropriate to comment on rumors about the show.”
