Legendary entertainer Bob Hope has died, just weeks after celebrating his 100th birthday.
The comic and film actor, regarded as one of the United States' greatest stars, celebrated his centenary in May.
He died of pneumonia in his sleep late on Sunday at his home in Toluca Lake, California, with his family at his bedside, his publicist said.
His sense of humour stayed with him until the end. When his wife of 63 years, Dolores, asked him where he wanted to be buried Hope quipped: "Surprise me!"
US President George Bush led the tributes, saying: "Today America lost a great citizen.
"Bob Hope made us laugh. He lifted our spirits. Bob Hope served our nation. We will mourn the loss of a good man."
President Bush also thanked him for entertaining "thousands of troops from different generations".
A Buckingham Palace spokeswoman said the Queen, who met Hope many times, was "very sad" to hear the news
and would be sending a private message to his widow, Dolores.
In May, birthday celebrations were held around the US and around the world - but, with failing eyesight and hearing, Hope was not well enough to attend them.

The performer was born in London but moved to the US aged four and became known as the "king of the wisecrack".
He became one of the US' favourites through more than 50 films - including the "Road" movies with Bing Crosby - plus television and radio shows.
He hosted more Academy Award ceremonies than anyone else, and was known for entertaining troops from World War II to the first Gulf War.
On Hope's 100th birthday, the President Bush established the Bob Hope American Patriot Award for civilians showing "extraordinary love of their country".
Other birthday celebrations had included the release of 101 balloons, the naming of a Bob Hope Square in Hollywood and Bob Hope day in 35 US states.
Hope is said to have joked to his family: "I'm so old, they've cancelled my blood type."
His wife of 69 years, Dolores, is 94.
Bob Hope was born Leslie Townes Hope at Eltham in south-east London in 1903, the son of a stonemason and a Welsh former concert singer.
He later changed his name to Bob, because "it sounded brisker".
After training as a tap-dancer, he became a major star in vaudeville, the American form of music hall which was then still hugely popular.
His fame grew on stage, radio and screen, and Hope became a close friend of presidents, including Kennedy, Nixon, Ford and Reagan.
He built up a personal fortune of an estimated $200m (£123m).
He is in the Guinness Book of Records as the most honoured entertainer in history after receiving more than 2,000 awards.
They included the Congressional Medal of Honour from President Kennedy and an honorary knighthood from the Queen in 1998.
But he never received the one he most wanted - an Oscar for acting.
Introducing the ceremony in 1968, he joked: "Welcome to the Academy Awards. Or as it's known in my house - Passover."
More than 89,000 pages of his jokes - most of them by a team of almost 100 writers - are preserved in the new Bob Hope Gallery at the US Library of Congress.
Five years ago false reports that Hope had died reached US Congress when Arizona Republican Bob Stump told colleagues: "It is with great sadness I announce that Bob Hope has died."
But Bob Hope's daughter, Linda, immediately denied the report, saying: "It's not true, he's happily having his breakfast."
UK wartime entertainer Dame Vera Lynn said Hope would be greatly missed.
"It's a period that meant a lot to so many people and he will be remembered by a lot of veterans for the work he did during that time," she said.
