It finally happened!
His official residence Clarence House released a statement from Charles and his wife Camilla, the Prince of Wales and Duchess of Cornwall, saying, "We're thrilled. We're both thrilled. We hope they'll be very happy indeed."
Kensington Palace revealed on Twitter that the couple would be conducting a photo call and a broadcast interview later on Monday.
Markle's parents, Thomas Markle and Doria Regland, wished the couple a "lifetime of happiness" via a statement from Kensintgon Palace.
"We are very excited for Harry and Meghan. It has been wonderful getting to know Meghan and to see how happy she and Harry are together," Prince William and Kate Middleton said in a statement.
The news comes after a whirlwind romance for the couple, who met in London in the summer of 2016.
Rumours of a possible engagement began to swirl after Markle, 36, shut down her lifestyle website The Tig in April, before ending her partnership with Canadian clothing brand Reitmans, for which she was a brand ambassador.
The couple also attended two weddings together that spring, including Harry's close pal's nuptials in Jamaica as well as Pippa Middleton's ceremony, prompting royal watchers to watch for an imminent engagement.

But it wasn't until Markle made the cover of the October issue of Vanity Fair, declaring that the couple was "in love," when most people assumed an engagement was inevitable.
"I can tell you that at the end of the day I think it's really simple," she told the mag. "We're two people who are really happy and in love."
She continued: "I'm sure there will be a time when we will have to come forward and present ourselves and have stories to tell, but I hope what people will understand is that this is our time. This is for us. It's part of what makes it so special, that it's just ours. But we're happy. Personally, I love a great love story."
Not long after the magazine hit newsstands, Markle and Prince Harry made their first public appearance together as a couple at the Invictus Games in Toronto in September, ensuring that naysayers had nothing left to say about the legitimacy of their relationship. Basically, they made it official.
Harry was even photographed kissing Markle on the cheek (in front of her mom!) while watching the Invictus Games closing ceremony.
In November, Markle completed filming on what's reportedly her last season of the TV show "Suits," and was seen moving out of her Toronto home to settle with Harry in the U.K. at his home Nottingham Cottage in Kensington Palace.
As we've previously reported, Markle, an American actress, could end up with the title Princess Henry of Wales once she and Harry, 33, wed.
Upon their marriage, Harry's title will also change, with many predicting that he will be named the Duke of Sussex, meaning that Markle could become the Duchess of Sussex, although Elle.com notes the prince could be given the Duke of Clarence, Oxford, Cumberland or Buckingham.
This will be Harry's first marriage and Markle's second — her first marriage, to American film and TV producer Trevor Engelson, ended in divorce in 2013 after two years.
