Stewart, Pattinson 'could be pregnant'

Kristen Stewart and Robert Pattinson are soon to become parents, according to reports.

Stewart, who has apparently been dating Pattinson since their near-kiss at the MTV Awards, is rumoured to be panicking about her late period and believes that her Twilight co-star is the father.

Australian magazine NW quoted a source as saying: "When [she] worked out she was late, she obviously started to thinking that she could be pregnant. And because of the timing, she thinks Rob could be the father."

A friend of the actress was also reportedly spotted buying a home pregnancy kit for her.

Pattinson was recently 'warned off' a relationship with his co-star by his family. Both actors' representatives declined to comment on the reports.
