The Prince of Monaco's best man will be his cousin, Chris LeVine. Miss Wittstock's witness will be Donatella Knecht de Massy, the wife of Sebastien de Massy, Albert's first cousin once removed.
Sebastien is the grandson of the late Princess Antoinette of Monaco. He is the son of the late Christine Alix de Massy and her first husband, American, Charles Wayne Knecht. Sebastien was born in Philadelphia in 1972.
It seems unlikely that the wedding will be televised live in the United States, although it will be on the news!
