Meghan Markle’s Royal Rage Over Prince Harry’s Invite To An Ex-Love

Prince Harry sparked a nasty spat with fiancée Meghan Markle — by inviting his former lover to their wedding!

The National ENQUIRER has learned the Meghan, furious that Harry asked socialite Cressida Bonas to share their big day, has demanded that the royal redhead follow a strict set of rules — or the May 19 nuptials are off!

“Meghan was blindsided by Harry’s invitation,” dished an insider. “She’s new to royal life and is feeling her way, trying to do everything right. But facing a showdown at her own wedding with Harry’s former flame is just too much!”

The lovebirds have already clashed over British actress-model Cressida after Harry was caught with her in December — while Meghan was visiting her mother, Doria Radlan (left), in Los Angeles.

Harry and Cressida dated from 2012 to 2014, and reunited on Dec. 5, singing Christmas carols with Kate Middleton’s family at St. Luke’s Church in London. The event raised money for a charity Harry supports. “Meghan’s really open-minded — she has an ex, too — and she took that encounter like a pro,” tattled the insider.

“But when Harry invited Cressida to the wedding, without telling her, Meghan’s radar went up! “She can’t help being suspicious.” The former “Suits” star laid out some ground rules, including no talking to Cressida at their wedding ceremony or the reception, except for a brief hello, and absolutely no hugging or kissing.

“I’m told Meghan made it clear Harry has to follow them if he wants the wedding to go ahead,” dished the source. “Harry, of course, agreed! He’s finally found the woman of his dreams. He wants nothing — and no one — to come between them.”
