Robert Pattinson's a godfather

Robert Pattinson has landed a new role - the Twilight star's become a godfather.

The Brit has been close friends with fellow actor Tom Sturridge and his family since their days at London's Harrodian School and Pattinson was asked to take on the new responsibility when Sturridge's sister, Matilda, gave birth to a son earlier this month (04Sep11).

The 25 year old, who is said to be dating his Twilight co-star Kristen Stewart, accepted the honour and celebrated the new arrival during a double date with Sturridge and his girlfriend, actress Sienna Miller, during a night out in the U.K. capital four days later.

A source tells Us Weekly magazine the two couples "looked happy" as they enjoyed drinks at the Groucho Club.
