Prince Harry and Meghan Markle have vowed to work together as a team when they embark on life as a married royal couple.

The newly-engaged pair shared their love story, with Harry declaring the "the stars were aligned" when he fell for the American actress.

Speculation is mounting over details of the church wedding next spring, with royal fans eager to find out where and on what date it will be held. 

The couple gave an insight into their 16-month romance in their first television interview, and described how they met on a blind date set up by a mutual friend.

Ms Markle told how she could not wait to say "yes" to the prince when Harry got down on one knee a few weeks ago as they cooked a roast chicken dinner at his home, Nottingham Cottage at Kensington Palace.

Indicating the depths of his feeling for his bride-to-be, Prince Harry said: "The fact that I fell in love with Meghan so incredibly quickly was sort of confirmation to me that everything, all the stars were aligned, everything was just perfect.

"It was this beautiful woman just sort of literally tripped and fell into my life, I fell into her life."

A few months into the relationship, Harry said he had to have "some pretty frank conversations" with Meghan about how her life may change when she entered the royal family.

He added: "But I know that at the end of the day she chooses me, and I choose her, and therefore whatever we have to tackle together or individually we'll always be us together as a team, so I think she's capable... she's capable of anything."

The couple told the BBC's Mishal Husain how Ms Markle had met the Queen twice, an individual she described as an "incredible woman".

The former Suits star was also a big hit with the Queen's beloved corgis, with the prince joking: "I've spent the last 33 years being barked at; this one walks in, absolutely nothing ..."

The prince praised the support of the pair's families and said he believed his bride-to be and mother Diana, Princess of Wales, would "be thick as thieves, without question".

Ms Markle's engagement ring features diamonds from Diana's personal collection, and a stone from one of their favourite places, Botswana.

Ms Markle will become an HRH and a senior royal after marrying Harry and joining the Windsors, and is expected to become a duchess, as Kate Middleton did when she became the Duchess of Cambridge after saying her vows in 2011.
