Yes, know but she did not get married. She lied or was too lazy to check English marriage law.
"Meghan Markle and Prince Harry have clarified that they didn't officially marry three days before their royal wedding, despite claiming they did in their interview with Oprah Winfrey.
In a new statement, the couple confirmed they exchanged unofficial, personal vows before their huge celebration in May 2018.
Speaking during the interview, Meghan said: "You know, three days before our wedding, we got married - no-one knows that.
"Just the two of us in our backyard with the Archbishop of Canterbury.
"We called the Archbishop and we just said, 'Look, this thing, this spectacle is for the world but we want our union between us'."
"So, like, the vows that we have framed in our room are just the two of us in our backyard with the Archbishop of Canterbury."
Harry also spoke about the secret 'wedding' later in the interview.
However the claim resulted in many questions from religious and legal experts, including the man who drew up their official wedding licence.
Stephen Borton, the ex-chief clerk at the Faculty Office of the Archbishop of Canterbury, said: “I’m sorry, but Meghan is obviously confused and clearly misinformed.
“They did not marry three days earlier in front of the Archbishop of Canterbury.
“The Special Licence I helped draw up enabled them to marry at St George’s Chapel in Windsor and what happened there on 19 May 2018 and was seen by millions around the world was the official wedding as recognised by the Church of England and the law."
Mr Borton was also reported to have said they could not have got married on the grounds of Nottingham Cottage as it isn't an authorised venue and three people isn't enough witnesses for a valid ceremony.
Copies of Meghan and Harry's wedding certificate also confirmed that they were legally wed at their public ceremony at St George's Chapel in Windsor.
A spokesperson for the couple has since confirmed what actually happened, saying they "privately exchanged personal vows a few days before their official/legal wedding on May 19". "
