Meghan Markle was pictured wearing Princess Diana's diamond and sapphire earrings as she attended an event with Harry in Canada.

The Duke and Duchess of Sussex were supporting their music mogul friend, David Foster, at his foundation's 40th Anniversary Celebration in Victoria, British Columbia, on Friday night.

The couple posed alongside record producer and composer David Foster, 76, and his wife, actress and singer Katherine McPhee, 42.

Prince Harry, 41, was dressed in a black tuxedo and a bow tie while Meghan wore a black maxi one-shouldered gown by Canadian designer Greta Constantine.

Meghan, 45, paid homage to her late mother-in-law, Princess Diana, by wearing her sapphire blue earrings, which stood out with her hair swept back in an updo.

The Duchess owns several pieces of jewellery from Princess Diana's personal collection and has previously worn Diana's earrings at public events.

Pieces from Diana's collection that Meghan owns include her butterfly earrings and matching cuff bracelet, a diamond tennis bracelet, her Cartier Tank Louis, and Diana's iconic aquamarine ring, widely dubbed her 'divorce ring'.

Canadian-American David Foster has won 16 Grammy Awards and 45 nominations across a career spanning four decades.

Meghan and Harry have been long friends of the couple, having previously been pictured on a double date with the couple.

In 2019, Foster arranged for the Duke and Duchess to stay at a close friend's mansion on Vancouver Island, telling the Daily Mail at the time: 'I felt honored that I was able to help Meghan there because I'm a Canadian, and we're a Commonwealth country - we're the Crown's.

'It's important to us, so I grew up with that kind of sentiment. I was really happy to be able to help them to find a respite just to take a little time off.'

Foster's wife, Katherine McPhee, has also known Meghan since childhood, having gone to the same school as her.

McPhee told Access Hollywood in 2020 of Foster and Harry's relationship: 'My husband has a really, really beautiful relationship with Harry.

'They're like, they're so cute. They're like father and son.'

'We just stay in touch with them. But mostly, Meghan and I knew each other from childhood, but really Harry and my husband are friends. It's really nice.'
