While Harry was busy with the polo match, the 35-year-old actress was cheering him comfortably from the Royal Box.
Markle's sis told Inside Edition: "I see Meghan and [Prince] Harry as definitely getting married".
Later, the 35-year-old Californian beauty was spotted kissing her boyfriend - with whom she's rumored to be moving in with later this year - in the auto park of the event, leading the British press to speculate the pair's PDAs are a sign marriage might be on the cards for duo.
The lovely actress of the series Suits who conquered the heart of Prince William's brother nearly a year ago, by its natural charm, will be able to fully enjoy the event.
But they're cute! Prince Harry and Meghan Markle finally made their first appearance together.
Meghan and Harry reportedly met last summer when a common friend introduced them. Although, Meghan may not be present at the ceremony at St. Mark's church in Englefield, England, but she will be able to attend the evening party afterward, according to People. She is lifting the "no ring no bring" policy so that Markle can attend at Harry's side. Harry allegedly passed on the royal Easter tradition, and jetted off to Toronto to spend the holiday with his girlfriend. The next one would be on May 20, when Pippa Middleton marries millionaire James Matthews.
This is the first public appearance by the couple, who usually keep a low profile. The brothers have, to date, raised over £10 million for charitable causes, the palace said. However, according to reports, she will not take part in the church service, but will accompany Harry at the reception.
"Despite a public fondness of Victoria Beckham dresses, Markle previously admitted to Glamour magazine that while she "love [s] Victoria Beckham dresses", she "[doesn't] have the long torso to support that silhouette".
