The singer is determined to snip Simon's locks off because his hair-do drives her mad.
She told ITV's This Morning: "I want to change that hair-do – sometimes it gets really flat like the Spongebob SquarePants character and I can't cope with that."
The 38-year-old also added to her feud with former X Factor judge Sharon Osbourne by saying she was just filled with 'hatred'.
Minogue said: "I don't really know what it was that upset her and she sort of goes on a lot about her hatred for me but I've got no time and energy to have enemies, it's just not my thing."
