A royal wedding is on the horizon! Prince Harry and Meghan Markle just marked their one year anniversary — and rumors are swirling that Prince Harry has already popped the question. The couple recently enjoyed a three-week stay in the African country of Botswana to celebrate the milestone.

But are Harry, 32, and Meghan, 36, engaged? “The celebration began almost the minute they touched down,” a source told Us Weekly. “Meghan was speechless and so touched.” The insider also revealed that while Harry intended to propose to the Suits star, he is keeping silent as the anniversary of his late mom Princess Diana‘s death approaches.

Previously, Life & Style reported that while Meghan is head over heels in love, she is getting cold feet when it comes to marrying into the royal family. “She is a smart, independent woman, and a life of shaking hands, cutting ribbons, and kissing babies in public just isn’t one she can envision for herself,” the source said. “She loves Harry and what they have together. But she keeps seeing glimpses of her future with him and wondering if it’s really a life she wants to lead.”

However, there is one thing she does know for sure. She will not be following in his sister-in-law Kate Middleton‘s footsteps. “Meghan has told Harry that she doesn’t want to be like Kate,” said a different source. “She wants to keep hold of her identity.”

This is not stopping Harry from picking out the perfect engagement ring for Meghan. According to the U.K.’s Express, he is creating a sparkler using an emerald from one of Princess Diana’s bracelets. “It is because of his grandad’s ill-health that he has broken the usual two-year romance protocol,” a royal insider said. “Harry thinks he got his ‘joker’ gene from Prince Philip and is desperate for his grandfather to see him get married while there is still time. They are very close.”
