The 72-year-old Republican is set to visit the U.K. on Monday, June 03, and will be meeting with British politicians and members of the Royal Family.
Just before the 2016 election, the 37-year-old said Trump is "divisive" and "misogynistic" and that she may stay in Canada, where she filmed "Suits" at the time, if he became president.
In an interview with U.K. newspaper The Sun ahead of his planned visit, Trump was asked if he was sorry he will not be able to meet Meghan, – who is on maternity leave after the birth of Archie last month.
The reporter then told the real estate mogul she "wasn't so nice" about him during the presidential campaign.
"I didn't know that. No, I didn't know that. No, I hope she is OK. I didn't know that, no," Trump said. "So what can I say? No, I didn't know that she was nasty."
He was later asked if having an American in the Royal Family was beneficial to relations between the United States and the U.K.
"I think it's nice. I think it's nice and I am sure she'll do excellently. She'll be very good. She'll be very good. I hope she does," Trump shared.
Prince Harry is expected to meet the U.S. President during his visit with wife Melania Trump, and the couple will also be guests at Queen Elizabeth's state banquet, along with other royals including Prince William and Catherine, Duchess of Cambridge.
