Meghan Markle's Co-Star Advised Her To Dump The Man She Was Dating Before She Met Prince Harry

Kristoffer Polaha has revealed the dating advice he gave his former co-star Meghan Markle before she met Prince Harry.

Polaha, 45, who starred alongside Markle, 41, in the 2016 film "Dater's Handbook," opened up in an interview with She Knows about his time working with the Duchess of Sussex.

"We had a great time...I called my wife and said, 'Meghan and I are going on fake date tonight.' We had dinner every night for three weeks. The only time we hung out was while we were filming so we had these 15 days," he shared.

The actor also revealed that he advised Markle to enjoy being single after she ended her first marriage to producer Trevor Engelson — and months before she met her now-husband, Prince Harry.

"She was dating a guy in Toronto, and she wasn't really into the dude, and I was like, 'You just got out of a marriage, why are you jumping into another relationship? Go be single, be free,'" Polaha told the outlet.

He continued, "She texted me in January and she was like, 'I took your advice. I'm single, I'm free. I'm going to see who's out there.' In March, I get this other text and she's like, 'Well, I met someone.' I said, 'Do you like him?' And she said, 'I kinda do.' And then, of course, it was Harry."

Markle began dating Prince Harry, 38, in the summer of 2016 after they were introduced through mutual friends. They announced their engagement a year later.

In May 2018, the Duke and Duchess of Sussex tied the knot at St George's Chapel in Windsor, England, and welcomed their now-3-year-old son, Archie, the following year. They have since welcomed a daughter, Lilibet, now 1.

British journalist and investigative reporter Tom Bower discussed Markle's dating life before she met Prince Harry during an interview about his latest unauthorized royal biography, "Revenge: Meghan, Harry and the War between the Windsors," in August.

Bower claimed that following her split from Engelson, Markle went on a manhunt for a new partner to "build her up." She had a relationship with Canadian chef Cory Vitiello following her divorce and lived with him in Toronto, according to the biographer.

The former BBC journalist and television producer claimed that Vitiello was a "good bloke [and a] nice man" but "wasn't good enough for an ambitious woman."

In his book, Bower claimed that Markle was still sharing a home with Vitiello when she went on her first date with Prince Harry in 2016.

According to the book, Markle's two-year relationship with the chef was already heading south at the time, and she allegedly broke up with him shortly after she was introduced to the prince. Vitiello was allegedly "relieved" because their final months together were not pleasant, Bower claimed.

International Business Times could not independently verify the biographer's claims.

Two years after tying the knot, Markle and Prince Harry announced their decision to step back from royal duties. They soon moved to California, where they have built a life with their two children away from the royal family.

Prince Harry is gearing up for the release of his memoir, "Spare," which hits shelves in January.
