Prince Harry and Meghan Markle have yet to announce an engagement, but that doesn’t mean fans of Britain’s royal family haven’t already started buzzing about their potential wedding.

As rumors continue to swirl about possible nuptials for the 33-year-old prince and his “Suits” actress girlfriend, “Prince Harry: The Inside Story” author and former The Sun royal editor Duncan Larcombe is dishing all about what he expects the affair will entail.

“There are a lot of unanswered questions about where and when the wedding will take place, how big it will be and who will be invited,” Larcombe told Life & Style in their Nov. 13 print edition. Still, the royal family expert says the event, should it occur, will be unforgettable.

“It’s going to be a dramatic lead-up to a unique and mind-blowing wedding,” he teased.

While Larcombe said specific details about Harry and Markle’s wedding are not yet known, the magazine claims to have some insight on their big day. Life & Style reports Markle, 36, has “control over” the guest list and is hoping to hire a wedding planner, while Harry is said to be “pushing for a wedding that’s more low-key” than his brother Prince William and wife Kate Middleton’s 2011 wedding.

As for a date, the magazine says Harry and Markle were initially hoping for a holiday wedding but have since pushed back their plans, reportedly because of the impending arrival of William and Kate’s third child. As previously reported, their baby of an undetermined gender is due to join their children Prince George, 4, and Princess Charlotte, 2, in April 2018.

If Markle doesn’t get her wedding planner, she can always lean on Middleton for assistance. Fellow author Andrew Morton, who has penned books on the late Princess Diana, says the 35-year-old Duchess of Cambridge is getting along swimmingly with her potential future sister-in-law.

“From what I hear, they get on really well and Kate is being very supportive,” Morton told the magazine. “Kate will love helping [Meghan] find her feet.”
