Prince Harry and Meghan Markle are believed to have first met in May previous year when he launched the 2017 Invictus Games in Toronto - the city where her TV show Suits is filmed.
"It was so sweet and natural and very romantic", she said.
In their first broadcast interview after announcing the news, Prince Harry and Ms Markle held hands as they discussed the moment of their proposal and their courtship. Designed by Prince Harry himself, the engagement ring features diamonds not only of substantial monetary value, but also of invaluable sentimental value as it is a tribute to his beloved late mother, Princess Diana, experts told MONEY.
The pair were introduced in July 2016 by mutual friends in London, Markle confirmed in September.
"But you know with the ring and with everything else that's going on I'm sure she's..."
In September, UsWeekly reported that a source said that Markle had met the Queen and "it went well". "This attractive woman just tripped and fell into my life, I fell into her life".
As she got to know Harry, Markle learnt about the huge amount of public scrutiny that the royals face, and she said she was not prepared for the level of attention their relationship would have.
"I did not have any understanding of just what it would be like", she said, saying there was a misconception that because she was an actress she would be used to being in the media spotlight.
The two were rumored to be planning a "non-traditional wedding" - unlike the lavishly royal wedding where Prince William and Kate Middleton tied the knot. The Suits star also said she's "very happy" about the engagement.
It is set to be a busy spring for the royal family, with the wedding and the arrival of a new child for William and Kate providing light relief from the dour political headlines as Britain negotiates Brexit. "Our daughter has always been a kind and loving person".
"We camped out with each other under the stars, we spent - she came and joined me for five days out there, which was absolutely fantastic", he said.
Indeed, the stunning diamond ring is fit for the incoming member of the royal family.
"Very first time we met", the prince said.
They are due to marry in the spring of next year.
