California - Kristen Stewart is pregnant? An Australian weekly magazine reports that the Twilight actress who's currently busy filming her biopic film "The Runaways" is pregnant with Robert Pattinson's baby.

The magazine's source claims that Kristen asked a friend to buy her a pregnancy test and described Stewart as "nervous about the whole situation". Not just the first gossip for Kristen Stewart and Robert Pattinson, last month when a magazine reported that Kristen dumped his long-time boyfriend Michael Angarano for her co-star love team Robert Pattinson. (yawn, so nasty!)
