Actress Kelly MacDonald won't strip for the camera again.

The 43-year-old actress, who shared a raunchy scene with Ewan McGregor in "Trainspotting", has since changed her stance on nudity and now has a 'bottom double' for any of her characters, reports femalefirst.co.uk.

"Generally, if you see a bit of flesh, it's not me. I used to not care about getting my photos taken, or any of that nudity thing. You'd expect that the more you did them, the easier they'd get. But that's not my experience," she told Radio Times.

Kelly also revealed that she doesn't need to "work herself up" for emotional scenes anymore as she has been acting for so long.

"'Trainspotting' was a number of years ago so I've got a bit of experience now. I don't wind myself up for big emotional scenes as I did maybe in my 20s and 30s. It's all in there and I am able to trust that now," she added.
