Daniel Radcliffe Has Quit Drinking After Partying 'Unsuccessfully' (VIDEO)

Daniel Radcliffe has already filmed the last installment of the 'Harry Potter' franchise, 'Harry Potter and the Deathly Hallows Part 2,' which hits theaters July 15. Lara Spencer reported Tuesday on 'Good Morning America' (weekdays, 7AM on ABC) that Radcliffe has also quit drinking, according to an interview in GQ magazine.

"He has just told GQ magazine that he is no longer drinking alcohol after partying quote 'unsuccessfully,'" she said. "He said he began drinking in 2009 while shooting 'Harry Potter and the Half Blood Prince' and realized he was relying on alcohol too much."

Spencer also marveled that the paparazzi never managed to catch Radcliffe with a drink in his hand. It helps if you have a cloak of invisibility to hide your hooch.
