Prince Harry got engaged to Meghan Markle on Monday (27 November) after a year and a half of dating. And, on the same day, the Royal revealed how his mother, Princess Diana, would have found his fiancé if she was still alive today.

Speaking to BBC, Harry, 33, revealed that his mother would have approved of the Suits star, 36, as her daughter-in-law, adding that she and his soon-to-be wife would have been "thick as thieves".

"I think she would be over the moon, jumping up and down, so excited for me. But then she probably would have been best friends with Meghan," he was quoted as saying by Entertainment Tonight.

While Harry is excited about getting married to Markle, he does miss his mother, who died in a car crash in August 1997. So, to keep her memory alive, Harry proposed marriage to Markle with a diamond ring made from Princess Diana's personal jewellery collection.

"So, it is days like today when I really miss having her around. I miss being able to share the happy news. But the ring and with everything else going on, I'm sure she's with us, jumping up and down somewhere," he said.

"The ring is, is obviously yellow gold because that's her favourite, and the main stone itself I sourced from Botswana, and the little diamonds either side are from my mother's jewellery collection, to make sure that she's with us on this crazy journey together," he was quoted as saying by Press Association.

Markle also echoed the same sentiment, saying, "She's with us."

"I think everything about Harry's thoughtfulness and the inclusion of that, and obviously not being able to meet his mom, it's so important for me to know that she's a part of this with us," she said.

"I think that being able to meet his aunts and also [her close friend] Julia, and just different people who were so important to his mom, I'm able to in some way know a part of her through them, and of course through him," Meghan said. "And it's incredibly special to be able to have this [her engagement ring] that sort of links where you come from, and Botswana, which is important to us. It's perfect."
