Rock matriarch Sharon Osbourne constantly infuriates her husband Ozzy by refusing to consult him about interior decorating decisions.

The reality TV star admits she takes it upon herself to give their Los Angeles home a makeover whenever rocker Ozzy Osbourne, who is nicknamed the Prince of Darkness, is on the road - and the ever-changing decor drives him "mad".

She explains on her show The Talk, "My husband can come home and he'll go into his gym and it's not a gym anymore. It's a bedroom. And he'll go into his study and where his desk was, there's no desk anymore.

"It makes me happy and he knows it's made me happy for 30 plus years, and I still keep doing it and he still keeps complaining. (He'll say), 'I thought the kitchen was blue?' 'No, it's red.' And then he'll go and look for a photo and say, 'See, it was blue! You are a liar!' And I'm like, 'I don't know!' And that gets him mad.

"And then he says, 'Why don't you ask me about decorating?' I say, 'Everything would be black!' I don't want a black house. It's a very personal attack for him that I would decorate without asking him."
