Amanda Seyfried: `I love sick jokes`

The Little Red Riding Hood actress admitted that she has a 'sick' sense of humour, and told Marie Claire that she is hard to shock.

'I think it comes from the morbid sense of humour my sister has,' she explained. 'I love sick jokes. I can't tell you, but what I will say is that nothing shocks me. Really nothing.

'Gross things make me laugh like a 12-year-old. Penis jokes make me laugh.'

Seyfried, 25, who is rumoured to be dating Ryan Phillippe, also revealed how she was afraid of sex when she was younger.

'Sex was meant to be a scary thing. Because of AIDS and pregnancy, we were constantly taught to stay away from it. Schools, videos, abstinence . It was just made out to be this very scary thing.

'My parents aren't very religious anyway, so that wasn't part of it. I think it was just the society where I grew up which made me look at it wrong. Also there were a lot of girls who got pregnant at school so that was terrifying.'
