Nicole Scherzinger has ''a few'' televisions - but doesn't know how to watch them.

The 'X Factor' judge rarely ever watches TV because she takes the programmes too seriously so it is never a relaxing experience for her.

She said: ''I never watch TV. I wish I could but my brain just doesn't work like that. I take it all very seriously.

''I believe in everything that's going on and I end up crying or getting really angry.

''The only time I ever sit down and watch a box set is when I'm travelling on a plane.

''As an actress, it is important to stay on top of the things that are out there and to see how they're being filmed.

''I have a few televisions at home but I don't even know how they work.''

The 'Poison' hitmaker is finding renovations on her new home to be all-consuming at the moment because she's determined to get it finished after so long without a proper home.

She told OK! magazine: ''I've been without somewhere to live for two years because my last house flooded so I had to move out.

''I've built somewhere new in Los Angeles but it's a work in progress, there's still a lot to do.

''I recently had two weeks downtime so I used it to make as many decisions about the house as possible. It's all I can think about at the moment.''

The 39-year-old singer likes to cook and eat out, but when she's working on 'The X Factor', she has to be careful about what she eats because she ''doesn't know'' how to restrict herself to a small portion.

She said: ''I don't cook very often but when I do I make sure it's the best.

''My favourite thing about being in the UK is going for a Sunday roast. It reminds me of Thanksgiving.

''I can't go for one when we're filming the live shows though or I'd have to waddle into the studios.

''It would make me so sleepy too because I don't know how to do small portions - I pile it all on.''
