Christina Ricci says Robert Pattinson is a "good kisser"

The 31-year-old actress locks lips with the British star in their new movie `Bel Ami` and she found him "lovely" to work with because of their shared sense of humour.

And she admits locking lips with Robert - who is dating his `Twilight` co-star Kristen Stewart - isn`t the hardest thing she`s ever been asked to do.

She said: "Everyone keeps asking me how it is to kiss Robert. He`s a good kisser. And I`m not being nice. It`s just like that

"He`s always the kind of guy that you can look at and go, `Oh God, this is uncomfortable`. And he`s really lovely to work with, especially in those kinds of scenes because he`s so quick to laugh at himself - and me. He`s very self-deprecating, as am I."

Christina has stripped for several film roles - including `Prozac Nation`, AfterLife` and `The Ice Storm` - and insists she has no problem with on screen nudity, though she admits she doesn`t know why she has had so many raunchy roles.

In an interview with Total Film magazine, she said: "I`m not really sure how that`s all happened. It goes with the territory sometimes. It goes with what a certain character is going through, and what happens in the story.

"I think it`s best not to have feelings about that kind of thing either way. If it`s required for the part, it`s required. If it`s not, then I don`t have to worry about being naked.

"I`m OK with it. I`ve learned to be OK with it. It takes a while to get used to, definitely, but you learn."
