If Harry, 32, was to marry Ms Markle, 35, it would mean he would follow in the footsteps of his brother Prince William, who married Kate Middleton in a lavish ceremony at the famous church in 2011.
(Married Wiki) Meghan Markle sparked engagement rumors with Prince Harry after closing her lifestyle blog.
Speculation that Prince Harry will be popping the question to girlfriend, Meghan Markle sooner than later is only being fueled by the reports that the prince has asked his grandmother, Queen Elizabeth to marry the American Actress. "An engagement is imminent", a source dished.
Things between Markle and Harry have been progressing since they announced their relationship a year ago.
As previously reported by The Mirror, Meghan Markle and Prince Harry won't be attending Pippa Middleston's wedding as fiance and fiancee.
Since then the couple has passed a considerable amount of relationship milestones: Christmas tree shopping together, meeting each other's families and most recently, making their first public appearance as a couple at the Audi Polo Challenge at Coworth Park Polo Club.
According to some, the opposite has occurred, if there is one person who knows how hard it is to blend in with the British monarchs, it is Parker-Bowles, which is why she has gone out of her way to embrace and guide Markle to make the transition as smooth as possible.
William and Kate also said "I do" at the Abbey.
With Harry planning to propose to Meghan in the next several weeks, there's a strong possibility that their royal wedding might take place this fall.
So far Prince Harry has made no indications that he plans on proposing to Meghan Markle, although many royal insiders believe that it might happen sooner rather than later.
