Katie Holmes isn't always the best bed partner for husband Tom Cruise - because she insists on wearing a facemask between the sheets.
The actress admits her beauty comes with a price - and her husband suffers more than most men.
Appearing on Friday's (01Apr11) Ellen DeGeneres Show, the Batman Begins star revealed, "Sk2 does these masks that are in a little package. It's white and you stick it on and then it kind of goes into your skin the whole night to the point where in the morning it's kind of dry and yucky and you just pull that part off and you're hydrated.
"I said (to Tom) I apologise but it's for the cause and I wanna look good in the morning, so this is the programme I'm doing right now."
And her recent attempts to moisturise her legs overnight were a disaster.
She explains, "I was conducting an experiment with myself. I'd noticed that my legs were very dry so I decided to dry brush and then put a lot of body oil on... I put too much on and I was like, 'Oh, this looks weird, like, I look like I'm in a calendar.'
"My husband comes in and says... 'What's with the oil...?' I was like, 'It's kind of supposed to be hot, right?' But he goes, 'Aren't the sheets gonna get all oily?'
"Lotion is better... It (oil) did get all over the sheets and then I was sticky and uncomfortable."
