The stars of Harry Potter & The Deathly Hallows: Part 2 have been busy all week doing press for the final movie in the franchise.
Last year, the cast tested their American accents with MTV host Josh Horowitz and this year, they were back for a second try.
This time, Tom Felton, Rupert Grint, and Matthew Lewis attempted to identify important American figures, say some important American phrases, and of course sing the most patriotic song ever…"Party in the USA."
Check out the hilarious clip below.
