Dozens of America's leading political and entertainment figures paid their respects to Ambassador Pamela Harriman on Thursday.
U-S President Bill Clinton led the service for Harriman at Washington National Cathedral.
The British-born socialite and one of the Democratic Party's most fervent supporters died in Paris last week from a stroke.
The rich and powerful were drawn together once more by Pamela Harriman on Thursday.
Celebrities from the political and entertainment world gathered at Washington National Cathedral to pay their last respects to the U-S ambassador.
Among the glittering crowd were Senator Edward Kennedy, Secretary of State Madeleine Albright and actor Gregory Peck.
Harriman died last week after suffering a stroke.
She was 76.
The British-born socialite is survived by her son, Winston Churchill, a British member of Parliament and her grandson, Randolph Churchill.
Randolph Churchill honoured his grandmother by reading from the essays of his great- grandfather, the former British Prime Minister Winston Churchill.
"We must reconcile ourselves to the mysterious rhythm of our destinies, such as they must be in this world of space and time."

Harriman often cited Winston Churchill as a personal inspiration.
Although the socialite appears to have been remembered best for her whirlwind romances and high-flying social life, Clinton praised Harriman for her work as ambassador to France and for her dedication to public service.
"She represented America with wisdom, grace and dignity, earning the confidence of France's leaders, the respect of its people, and the devotion of her staff."

Harriman's remains will be buried on Friday next to those of her third husband, former New York governor ambassador W. Averill Harriman, at Arden, the family estate located north of New York City.
