Slowly but surely, Meghan Markle is winning over the royal family.

Just one week after Britain's Sunday Express newspaper broke the news that Prince Harry has quietly been dating the American, who stars on USA Network's "Suits," it's published a new report revealing that the actress has become good friends with her boyfriend's cousin, Princess Eugenie.

Eugenie, 26 -- the daughter of the Duke and Duchess of York -- has apparently told friends that Harry, 32, and Meghan, 35, are "the perfect match."

The Sunday Express also reports that last weekend, Eugenie and her boyfriend, Jack Brooksbank -- who's reportedly planning to propose soon -- flew to Toronto, where Meghan lives and shoots her show, and partied with her and Harry at a Halloween bash hosted by the swank members-only club Soho House on Oct. 30.

"They all had a great time and Harry was delighted Eugenie and Jack could join them," an insider told the Sunday Express. "They have all become great friends. Eugenie loves Meghan to bits and believes she is perfect for Harry."

The insider added, "They are thick as thieves and may even all go on holiday together soon. Eugenie has lots of friends who could let them stay and be discreet, away from prying eyes."

But that's not the only time the royal cousins hung with their significant others together.

Harry and Meghan, who recently started following Jack on Instagram, also went on a double dinner date with him and Eugenie in London in October, the paper reports.

The newspaper also insists that reports claiming Meghan, a divorcee and devoted humanitarian who's worked with the UN, has met Harry's father are untrue. "Although Meghan hasn't met the Queen or Prince Charles yet, she has very much been welcomed into the royal fold thanks to the double dates with Eugenie and Jack," another source explained.

A friend believes it's only a matter of time until Meghan and Harry are photographed together.

"Meghan is a lovely, outgoing person and she's not going to want to hide away from the world," the friend told the Sunday Express.

"She was happy to see Harry secretly, but now that their relationship is out there, it's only a matter of time before they are seen on each other's arms."
