Prince Harry, fifth in line to the British throne, will marry American actress Meghan Markle in the spring, royal officials announced Monday, confirming months of speculation. The couple posed for photographers on the grounds of Kensington Palace hours after their engagement was announced by Harry's father, Prince Charles.

Palace officials said Harry designed the ring himself. It features two diamonds that belonged to his late mother Princess Diana, and a central diamond from Botswana, a country he and Markle have visited together.
