Actress Kristen Stewart, who is dating her Twilight co-star Robert Pattinson, may be inspired by her parents' stable marriage, but she is not ready to tie the knot for now.

"I'm not ready to get married, but I have a really great family and I'd like that too someday, sure," she said.

"I believe in marriage. Whatever you want to do, you know?"

Stewart also confessed that she and her parents never talked about sex as she was growing up because she already "knew everything".

"I knew everything from the word go. I'm really, really mature that way. I never had 'the talk'. I could never have 'the talk.' I didn't need it," she said.

Meanwhile, Pattinson has spoken of the differences between himself and Kristen, saying that they have opposite approaches in dealing with their movies.

"Kristen's mind works completely differently so she feels things immediately and I like to be much more cerebral about things," he said.

"I'm the complete opposite of Kristen. I don't feel confident unless I know more about the reasons to be doing things."

Although Pattinson still has Stewart's attention, their Twilight co-star Ashley Greene said that she would never be attracted to him.

Greene, who plays Alice Cullen in the franchise, know why people are attracted to the British actor, but after working with him on the movies, she says she sees him only as a colleague.

"I understand. I don't see him on the same level, he's just this guy I made a film with," she said.

Greene also described how much she enjoyed getting bruised while having fight training for scenes in The Twilight Saga: Eclipse.

"We took each character and keyed the fight sequence to their characteristics, so Alice was very dancer-esque almost like 'The Matrix'. I was sore, and I was bruised, and I loved every second of it," she told Total Film magazine.

She is confident that the action-packed third installment of the Twilight series will be a winner with both men and women.

"I definitely think it's a movie that the girls are going to enjoy because there's Rob Pattinson, and there's also a lot that the guys will enjoy because it's high drama, high action," she said.
