The news first broke earlier day when veteran royal reporter Richard Kay for Daily Mail, wrote that the pair became engaged over the weekend.
Mr Matthews, 40, asked Miss Middleton’s father for permission before he proposed, the Daily Mail reported, because he is a “traditionalist” and “wanted to do things properly”.
Middleton, 32, and Matthews, 40, first dated in 2012 before parting ways – and reunited in 2015. The pair have been spotted vacation in St. Barts with the Middleton family, and most recently looking loved-up court-side at Wimbledon.
