Prince Harry has a close bond with his 'other father' David Foster – whose wife acted alongside Meghan Markle in their school musicals.
The Duke of Sussex, 37, was snapped playing a game of polo in California on the weekend and composer David Foster, 72, was there supporting him.
David has always played a key role in Prince Harry's life and is looked up to by the ex-royal as a 'father figure', according to reports.
The composer, who is a year younger than Prince Charles, also helped Harry and Meghan find a home in Canada before they relocated and settled down in California, Mirror reports.
Katherine, David's wife, described the multi-million dollar mansion hunt for Harry and Meghan in an interview with Access Hollywood: "David is the resource guy.
"He knows all the places. He loves to help people. We just hope they end up somewhere where they feel like they can really settle down."
Harry has reportedly seen his relationship worsen with his father Charles over the past few years but has seen his bond with David grown stronger.
Katherine went on to add that her husband and Harry share a special bond, saying: "My husband has a really, really beautiful relationship with Harry. They're so cute.
"They're like father and son."
