Sir Anthony, Citizen Hopkins

Sir Anthony Hopkins has become a Yank, but he hasn't given up his British citizenship or his title.

"He has taken a dual citizenship. He hasn't renounced his British citizenship," his spokeswoman, Catherine Olim, said Thursday.

U.S. District Judge Margaret Morrow administered the oath of citizenship on Wednesday. Reporters and photographers were barred at the request of Hopkins, who made no public statements about his new national allegiance.

The Silence of the Lambs star, who received a knighthood eight years ago, was joined by friends, including Steven Spielberg, during the courthouse ceremony.

"This has been his home for some time and it seemed like the right thing to do," the spokeswoman added.

Hopkins, 62, was knighted by Queen Elizabeth II in 1993, giving him the right to use "Sir" before his name. That title remains, Olim said.
