Kristen Stewart, who is rumoured to be dating her Twilight costar Robert Pattinson, says she does not dream about having a white wedding like most girls her age.

"Not at this point of my life," she told an interviewer when asked about her thoughts on marriage. She, however, does think about having a baby.

"Maybe I'm completely different from everyone else. There are a lot of girls who can't wait to get married and plan their wedding a long time in advance. I'm not like that. I do want to start a family at some point, but I don't know when," Kristen said.

The 20-year-old actress still refuses to talk about her romance with Robert, and only refers to him as a "good friend".

"At the beginning of the films there wasn't a relationship at all, because we (me and Robert) didn't know each other at all, but now it's all different," she said.

"We've shot all these films together and he's become a good friend of mine. Taylor Lautner and Rob are incredibly important to me. They don't get on my nerves. We're always honest with each other without having to worry whether we're hurting each other's feelings."
