London, March 21 - Mark Owen is being kept in virtual isolation in rehab, with no visits from pals or fuming wife Emma.

Owen, 38, is receiving help for his issues with booze, drugs and depression at the clinic.

"Doctors want to focus Mark's mind and shake up his normal routine and any emotional crutches - even coffee and sugar are banned," News of the World quoted a source as saying.

"Everyone's treated the same, including celebs," the source added. (ANI)
