The ceremony was officiated by Downey's Angel costar, Della Reese, 75, who is an ordained minister.
Burnett's sons from a previous marriage, James, 13 and Cameron, 10, acted as best man and ring bearer. Downey's daughter from a previous marriage, Reilly, 10, was a bridesmaid.
Downey hired an airplane that flew overhead with a banner that read, "... and they lived happily ever after" as a surprise for Burnett.
The couple had been Malibu neighbors for years and finally started dating in January of 2004. They were engaged last November during a Thanksgiving family vacation in Zihuatenejo, Mexico. They plan a 10-day honeymoon to Jordan and London.
