Sandra Bullock finds naked scenes funny.

The 'Heat' actress says she wouldn't ever try to be sexy on screen but thinks nakedness can be hilarious in movies.

Speaking on 'The Graham Norton Show', she said: ''There's nothing sexy about it at all--it's funny. It's not intimate.

''I don't do naked for sexy. Naked only works for me in the funny. On film, not in real life!''

Along with stripping off for 'The Proposal' with Ryan Reynolds, Sandra also filmed a funny video in October 2012 which showed her and chat show host Chelsea Handler getting into a fight while they were in a shower.

Sandra also claimed she would never make a sex tape because she doesn't look good during sex.

She added: ''If you're having sex and you get recorded, and you don't know you're being recorded, my guess - not that I've ever done this - is that you don't look good doing it!

''I can't imagine, that someone would look good whilst having intercourse not knowing they're filmed. But you notice, anytime someone has a sex tape, it's beautifully lit, they got the good angles, it's like, 'that's right,' over the shoulders are great...Who does that? Who does that?!''
