The women fell out when they were both judges on the UK show, with the Osbournes matriarch branding Dannii 'useless:, The Mirror reported.
Sharon is rumoured to be about to make a return as a guest of Louis Walsh and Dannii said that’s fine as long as she stays out of her dressing room.
She told the UK newspaper: “I’m not surprised Louis brought Sharon back, she is great value. As long as she’s kept away from me, I don’t care what she does. My dressing room is a Sharon-free zone.”
Dannii revealed details of the feud in her recent autobiography, claiming Sharon “bowled in” to her dressing room and shouted at her in the 2007 series.
In March, Sharon was quoted as saying: “She wasn’t so much a dim bulb as a bulb in a power cut. F***ing useless.”
