SIMON COWELL has criticised SHARON OSBOURNE for launching a scathing attack on fellow THE X FACTOR judge DANNII MINOGUE, branding her behaviour inappropriate and "wrong".

The media mogul is said to be so furious with Osbourne, 55, in the wake of her verbal tirade on the Australian singer made on British TV last week (13Dec07) that he is may drop the rock matriarch from the next series of the talent competition.

Cowell, 47, says, "You see a grown-up Sharon behaving like this in public. I think it’s wrong. Certain things should be done behind closed doors - the limelight shouldn’t be taken from the contestants. "I wish Sharon would ask my advice before she does things instead of trying to deal with it herself."
