Has Robert Pattinson stayed in touch with his Harry Potter and the Goblet of Fire costar Daniel Radcliffe? Nope!

"I won't pretend we're best mates or knew each other really well but we really enjoyed working with each other, or at least I enjoyed working with him!" Radcliffe said during a press conference for Harry Potter and the Half-Blood Prince. "He's doing brilliantly, which is fantastic."

In the 2005 film, Pattinson played the role of Cedric Diggory. Since then, he has become a household name playing vampire Edward Cullen in the Twilight movie franchise.

Radcliffe, however, revealed that he hasn't seen Twilight and explained, "The thing that is interesting for me, is that Twilight is the only other franchise that comes close to Potter in terms of the mania that surrounds it, the attention that the leads get and just how global it is."
