'Harry Potter and the Deathly Hallows Part 2' Cast Try to "Talk American"...Again!

MTV's Josh Horowitz is at it again making the stars of Harry Potter try to "talk American." He even has them try to sing along to Miley Cyrus' "Party in the U.S.A!"

In another installment of MTV's "American Talk," Josh gives Rupert Grint, Tom Felton and Matthew Lewis some tests to see if they can speak "American."

Josh tested the Harry Potter stars on their knowledge of American celebrities and somehow slipped in an image of Robert Pattinson!

"Edward Cullen, is it?" Tom asked. "Is that right?"

"Close. That is Robert Pattinson, our prettiest most adorable American," Josh jokes.

"He's a beautiful American," Tom agreed. "He looks gorgeous."

But perhaps the best test was when the three guys had to sing "the most American of songs."

"Oh, say," Tom begins.

"Nope," Josh corrects him. "This is 'Party In the U.S.A.' by Miley Cyrus."
