Pop stars, artists and royalty were among the guests at York Minster as singer Ellie Goulding married Caspar Jopling.
Miss Goulding, 32, became engaged to the 27-year-old art dealer last year.
Sarah Duchess of York and her daughters, Princess Beatrice and Princess Eugenie of York, were among the guests.
A reception was held afterwards at Castle Howard, near Malton, about 15 miles (24km) from York.
Miss Goulding arrived at the cathedral in a blue Volkswagen camper van to be greeted by cheers from the large crowd.
Earlier downpours of rain had cleared by the time most guests arrived, in buses, for the 15:00 BST ceremony.
The princesses and their mother were greeted by Jack Brooksbank, Princess Eugenie’s husband, who was one of the groomsmen.
Leading the celebrities arriving at York Minster and thrilling the crowds were Katy Perry and Orlando Bloom.
The world of music was also represented by James Blunt while other showbiz guests included Sienna Miller, Jo Wicks, and comedian Jimmy Carr.
York Minster is the largest gothic cathedral in the UK and normally a couple must have a “connection” to the minster and apply for a special licence to marry there.
A minster spokesperson said the couple had “fulfilled” the qualifying criteria.
Miss Goulding was raised in Herefordshire, however Mr Jopling has strong connections to Yorkshire.
His father is the Honorable Nicholas Jopling, of Thirsk while his mother Jayne Warde-Aldam and his step-father own Frickley Hall, a Georgian stately home near Doncaster.
