And bookmakers have now chose to pull all bets on when the engagement will take place, amid rumours that the BBC is now primed for the announcement.
"It's been an absolute pleasure and honour being your "STAND-IN" for the last 2 seasons @meghanmarkle".
Ever since Harry's remarkable attack in November 2016 on the media's treatment of Meghan, in which he confirmed for the first time that they were dating, it was clear that their romance could likely lead to the American actress someday walking down the aisle of Westminster Abbey. "Wishing you all the happiness in the world Bella".
Rumors have been flying for months now that Prince Harry was preparing to pop the question to Meghan Markle.
A weekly overview of the chatter from Kensington Palace and beyond.
Meghan and Harry first met in July of a year ago but the relationship wasn't officially confirmed by the palace until November when it issued a statement asking the media to give the actress privacy. At this time, Ladbrokes has actually closed down betting on all aspects of the Meghan Markle, Prince Harry relationship because the odds are no longer in their favor.
Meanwhile, the actress is allegedly living at the Nottingham Cottage, in the wing reserved for Prince Harry's residence in Kensington Palace, where Prince William and Kate Middleton now live. "It's always been a case of when and not if Harry and Meghan announce they are engaged, and all bets are off for a 2018 wedding". Bogart and Guy will allegedly join the palace dog pack in early 2018 and make friends with the royal Corgis of Queen Elizabeth. Paddy Power is still taking bets on a number of Prince Harry/Meghan Markle topics.
