Clairvoyant Sally Morgan, well known as Princess Diana's trusted psychic, says Meghan Markle and Prince Harry will go the distance.
The medium explained how she can see a lasting and happy marriage between the former senior royals.
The 69-year-old is famed for her predictions about the royal family, some of which have already come true.
She had a premonition about Princess Diana's death, a year before the tragic Paris crash which also look the lives of Dodi Fayed and driver Henri Paul.
Psychic to the stars Sally was on The Morning Show and told hosts Kylie Gillies and Matt Shirvington that what she sees ahead for Harry and Meghan.
She said: "I see for her that she's got great love in her marriage with him.
"I know lots of predictions say it won't last, but I do think their marriage will last.
"It will run its full course, and I think there's absolutely no doubt she has laid down the law and it's going to be how she wants it.
"There's no doubt about that," she told the US hosts.
The year prior to Diana’s death in 1997, a premonition about an accident came to her.
Sally, who was Diana’s psychic for four years, revealed the information in a reading with one of her sisters.
She explained how she saw a body being pulled out of a car in a tunnel, but at the time thought it might be the Queen.
On Friday's show, Sally talked about her connection with the late Princess of Wales.
Sally is close to Diana's sister, Lady Sarah McCorquodale, and she added: "It's only now that I look back and realise just how amazing it was to be able to speak to her for four and a half years, almost daily.
"Lady Sarah was her lady-in-waiting, so when she came to London - she lives in Norfolk - to accompany the Princess of Wales on functions, she would pop in and see me.
"I was very close to them both for a long time."
