Actress Kristen Stewart laughs off rumours that she's pregnant with Rob Pattinson's baby, say sources.
"Joan (Jett, the actresses character in The Runaways) and Kristen managed to have a laugh about the rumor," the New York Daily News quoted a source as telling Life & Style.
"Kristen just thought it was ridiculous," the source added. An Australian tabloid recently claimed that the Twilight star was expecting a child with Pattinson.
Rumours about them being an item have been circulating ever since they starred together in the hit film Twilight last year.
