Heidi Klum exchanged wedding vows with Tokio Hotel musician Tom Kaulitz on a yacht in Capri, Italy, on Saturday.

People.com said the former "Project Runway" host and "America's Got Talent" judge wore a strapless white gown with long sleeves and a floral design for the occasion, which took place months after the couple legally married in the United States.

The groom wore a white suit with a light blue shirt and pocket square.

UsMagazine.com said Kaulitz's twin brother Bill officiated the service.

Among the guests were Klum's four children.

Klum, 46, was previously married to celebrity hairstylist Ric Pipino and singer Seal.

Kaulitz, 29, is divorced from Ria Sommerfeld.
