Buffy star Sarah Michelle Gellar says she loved playing a porn star in her latest movie role and says she might have found her true calling.

The actress played Krysta Kapowski in the film Southland Tales and thinks she was perfrect for the role.

She said: �When you look at me you just think - porn star! It�s like a calling really!"

But she says that even though she was playing a porn star she still refused to go topless.

"My trainer said to me: 'So we've got to start getting you in shape for this topless scene.' And I was like: 'I'm sorry, what?' And he said he had read somewhere that I had said I really wanted to take my top off in a movie.�

She added: "But I immediately said to him: 'To know me is to know that's not true.'"
