While confirming nothing, it's at least a confirmation that the palace is painfully aware of the fevered reporting on the couple, who were widely reported as likely to announce their engagement after Queen Elisabeth and Prince Philip had their 70th wedding anniversary on November 20.
Speaking with various British outlets, a spokesperson for the Royal Family said they "would not give a running commentary on Harry's love life", reported Vulture.
The two reportedly told Queen Elizabeth and the entire Palace brain trust about their engagement in a hush-hush meeting. Radar Online reported that Prime Minister Theresa May has cleared her public schedule for Tuesday, as she has reportedly been informed that the announcement will take place on that day.
Bookies have suspended bets on the new royal wedding announcement, with Ladbrokes saying they believe it is "imminent".
British Royal family issues official statement on Prince Harry and Meghan's engagement
Royal watchers expect it to happen on Tuesday as it's pretty much tradition - both Prince Charles and Prince William told the world about their engagements on that day of the week.
If you need any more convincing, Kate Middleton showed off the same sort of protection after she became engaged to Prince William in 2010. The actress recently quit her television series, Suits and has reportedly moved to the United Kingdom with her dogs to be with Prince Harry.
In another sign of a royal wedding ahead, Markle was accompanied by bodyguards from the Metropolitan Police's Protection Command on Tuesday for the first time.
Things have got increasingly more serious between the pair in recent months, with Meghan, 36, reportedly set to quit working on her legal drama "Suits" in favour of a life in the United Kingdom with Harry, where she has also reportedly relocated her pet dogs.
