Robert Pattinson, Kristen Stewart Getting Married?

Ian Gavan/Getty Images(NEW YORK) -- Are Twilight stars Robert Pattinson and Kristen Stewart tying the knot?

The answer is -- not yet, but Pattinson says in an interview with BlackBook magazine that there are so many rumors out there, his own mother even started to believe them.

Pattinson explains, "There was a magazine, with these pictures, saying I was getting married. No one ever knows what is true or what isn't.  Even my own mum called to ask me if it was true."

The still single Pattinson will next be seen on the big screen in Cosmopolis, which opens August 17.
