The "Piano Man" has said "I do" for the third time.
Billy Joel, 55, married his fiancee, Katie Lee, 23, in a sunset wedding Saturday at his 15-acre waterfront Center Island estate in Long Island.
Lee wore a custom-made Oscar de la Renta gown, Jimmy Choo shoes and a borrowed 50-carat diamond necklace during the traditional ceremony. At the reception, guests were treated to a Tuscan-themed dinner and an impromptu set by the Piano Man himself, who performed some 20 songs with the band, including "Try a Little Tenderness", which he dedicated to his new wife.
Among the 210 attendees: Howard Stern, Paul Reiser, Don Henley and Joel's second wife, Christie Brinkley. Their daughter Alexa Ray, 18, served as maid of honor.
Lee, a native of Huntington, W.Va., graduated from Ohio's Miami University and is a a restaurant correspondent for the PBS show George Hirsch: Living It Up!. She and Joel began dating last year; he proposed to her in January while they were vacationing on St. Bart's.
Besides Brinkley, to whom he was married from 1985-94, Joel was married to business manager Elizabeth Weber from 1973-82.
