Former first lady Nancy Reagan (search) slipped and fell early Thursday in her London hotel room and was taken to a hospital for examination and released, her chief of staff said.

Mrs. Reagan, who turns 84 on July 6, wasn't hurt and doctors sent her back to the hotel for rest, spokeswoman Joanne Drake said from her office at the Ronald Reagan Presidential Library in Simi Valley, Calif.

"She took a fall at the hotel. She had some pain and they took her to the hospital," Drake said, adding Mrs. Reagan was on an approximately 10-day, private vacation to Britain. Mrs. Reagan was released a short time later.

"She will be following her doctor's advice to limit her activities over the next two weeks until the pain subsides and full mobility returns," Cathy Busch, an aide traveling with the former first lady, said in a statement.

Mrs. Reagan plans on continuing her stay but her schedule will be lightened, Drake said.

The former first lady had already had tea with longtime friend Lady Margaret Thatcher (search) as well as Prince Charles (search) and the Duchess of Cornwall (search) at Clarence House.
