Ever since Prince Harry and actress Meghan Markle reportedly started dating, their every move makes it to the headlines.

Just recently, their names popped up in the various reports again, following the prince's low-key birthday celebration.

A source close to the 36-year-old "Suits" actress reportedly revealed to E! News that actress and her royal boyfriend, "quietly celebrated his birthday together on Saturday as she wouldn't be with him on the day of."

Prince Harry turns 33 years old this Saturday, Sept. 15, but the couple reportedly celebrated in advance because of Markle's other engagements on the day of his actual birthday.

The source also said: "Harry doesn't like to make a fuss of birthdays so he liked that it was just the two of them. Sometimes it doesn't have to be a huge thing with a group of friends."

They have yet to make their official debut, but the two have been an item for a while. Rumors about the royal popping the big question have also been circulating for several months now, and the latest news is that the Palace is allegedly preparing for Markle and Prince Harry's much-awaited engagement.

According to The Mail, an official announcement from the palace regarding the couple's engagement is already in the works. They are apparently taking their time in order not to overshadow the 20th death anniversary of Princess Diana and the announcement of the Duchess of Cambridge Kate Middleton's pregnancy.

The first step that they are said to be taking is for the Markle and Prince Harry to make their first public appearance together.

The two are expected to make their relationship "royally official" on Sept. 23, at the Invictus Games in Toronto. This is thought to be the perfect way to properly introduce themselves to the world as a couple, considering that the event is one of the prince's favorite projects and the location is nothing new to the actress as she had spent a lot of time in Toronto filming "Suits."

It is believed that after this appearance, their engagement will finally be announced.

In Vanity Fair's October cover story, Markle opened up about her relationship with Harry.

"We're two people who are really happy and in love," she expressed. "We were very quietly dating for about six months before it became news, and I was working during that whole time, and the only thing that changed was people's perception. Nothing about me changed. I'm still the same person that I am, and I've never defined myself by my relationship," she added.
