Botswana- Prince Harry and Meghan Markle were photographed on the airport's tarmac on Friday, by the Sun. The couple is spending a romantic weekend on the African continent, to celebrate Markle's 36th birthday. Of course, it could be just that. A birthday celebration for the American "Suits" star. However, rumors about a possible proposal are also spreading like wildfire. And the best part? Prince Harry was allegedly spotted earlier this year, designing an engagement ring with the Queen's jeweler, Harry Collins.

Why Botswana?

Prince Harry has oft spoken of his love for the African continent.

And while he has many charity organizations, such as Sentebale in South Africa, he claims that Botswana is one of his favorite destinations. He has mentioned that he has several friends and acquaintances there that help him avoid the paparazzi and have a bit more privacy than usual.

Furthermore, Harry has spoken of his wish to one day expose his children to Africa, in the hopes that they will share his love for the wild continent. It is therefore fitting that Harry take his potential wife-to-be to visit what he describes as his "second home." Harry and Markle have been getting more and more serious of late, and it has been speculated that Harry needs Africa's privacy so that he can finally pop the question.

After all, Prince William chose to propose to Kate Middleton atop the solitary Mount Kenya, according to ABC News.

What would the wedding look like?

Of course, a wedding for a royal is nothing simple. Prince Harry, who is fourth in line to the throne, would have first to ask the Queen's permission. Another obstacle would perhaps be that Markle was once married to Trevor Engelson, a film producer.

The Royals aren't so keen on marrying divorcees, but then again, Prince Charles was allowed to marry Camilla Parker-Bowles, who had also been married before, so perhaps this won't be much of a problem for Prince Harry.

And the best part? Harry was already spotted designing an emerald and diamond engagement ring from one of Diana's bracelets, according to several British newspapers.

So, perhaps the Prince already has the Queen's blessing. Prince Harry and Markle's wedding would inevitably turn out to be every bit as glamorous as all the other royal weddings of late. According to the Mirror, the ceremony would have to take place in one of Britain's most prominent cathedrals. It is likely that Prince William would be Harry's best man and that some of the notable guests would include Serena Williams and Meghan's stylist and close friend, Jessica Mulroney.

A royal engagement would be some of the best news this year!
