The Duke and Duchess of Cambridge will be in the Los Angeles area from July 8 to July 10 following a tour of Canada. Officials have not said what the couple will do in L.A.
It will be the first official overseas trip for the royal couple, who were married at Westminster Abbey on April 29.
The royal couple will visit Canada from June 30 to July 8, taking in the country's north, south, east and west.
Palace officials said the couple will visit Canada's capital, Ottawa and the surrounding region; Montreal and Quebec City in the francophone province of Quebec; Charlottetown and Summerside on Prince Edward Island; the Northwest Territories capital of Yellowknife and the oil boom town of Calgary, Alberta. Their Alberta visit coincides with the opening of the city's world-famous rodeo event, the Calgary Stampede.
Their first event of the tour will be taking part in Canada Day celebrations on July 1 in Ottawa with Canadian Prime Minister Stephen Harper, Heritage Minister James Moore said.
"We expect tens of thousands of people to come out. It will be in fact, I think, perhaps the largest Canada Day celebration in history on Parliament Hill," Moore said.
The couple will also help open the Calgary Stampede when they are in Alberta, he said.
