The 25-year-old American actress says it takes a lot to shock her when it comes to morbid humour. The Hollywood star blames her alternative sense of fun on her sibling and says her ability to laugh at risqu jokes stems from her.

I have a twisted side. I think it comes from the morbid sense of humour my sister has. I love sick jokes. I cant tell you what, but what I will say is that nothing shocks me. Really nothing, she told Marie Claire magazine.

Amanda compares her sense of humour to that of a 12-year-old. She finds gross things funny, explaining stereotypical male jokes are what she likes the best.

Gross things make me laugh like a 12-year-old. Penis jokes make me laugh, she added.

The stunning star is best known for her roles in Dear John, and Mamma Mia! and can be seen in dark fantasy film Red Riding Hood. She plays a young girl who upsets her family by falling for an orphaned woodcutter. The film is set in a medieval village that is terrorised by a werewolf and is directed by Catherine Hardwicke.
