Daniel Radcliffe & Rupert Grint party!

Daniel Radcliffe and his Harry Potter co-star Rupert Grint partied together over the weekend.

The pair headed out to Patch Nightclub in London for a night of partying, after doing press all day for Harry Potter and the Deathly Hollows.

Daniel is turning into quite the party animal – he recently celebrated his 21st birthday with a trip to St. Petersburg, Russia, followed by a birthday bash with his friends in London.
