Prince Harry became so captivated by American actress Meghan Markle that he didn’t hesitate to drop the L-word just three months into their whirlwind romance.

The claim is made in the upcoming bombshell book “Finding Freedom,” written by royal reporters Omid Scobie and Carolyn Durand. Numerous palace insiders came forward to the two journalists and detailed what led to the Duke and Duchess of Sussex’s departure as senior members of the British royal family.

The couple currently resides in Markle’s native Los Angeles with their son Archie.

On Monday, the U.K.’s Daily Mail reported that an excerpt from the book revealed the British prince left his first date at Dean Street Townhouse with the former “Suits” star in a “trance.” Markle, 38, later told friends “this could have legs.”

Markle, a divorcee, allegedly told a pal that she’d be happy for “a nice English gentleman to flirt with” before embarking on that fateful trip to London where she met Harry.

PRINCE HARRY 'HAD FALLOUTS WITH HIS OWN CIRCLE' OVER MEGHAN MARKLE 'PREJUDICE,' BOOK CLAIMS

Meanwhile, Harry told friends after their hours-long date that Markle was “ticking every box.”

According to the outlet, Markle was secretly taken to Kensington Palace just one night after date number two, where Harry attempted to “impress her with tales about his work and life,” which he described as a “little mad.”

Six weeks later, Harry told Markle he wanted to take her on a trip and asked her to fly to London.

The outlet claimed Markle flew in from Toronto and spent a night with Harry at Kensington Palace before the pair jetted off to Botswana.

“She came back smiling and just completely spellbound,” one friend remarked.

“By then, they were each already dancing around the idea that this just may be a forever thing,” chimed another friend.

Harry also embarked on commercial flights to Toronto where he would spend time with the actress.

And three months into their courtship, Harry told Markle “I love you.”

KATE MIDDLETON 'BARELY ACKNOWLEDGED' MEGHAN MARKLE DURING ROYAL FAMILY FALLOUT: BOOK

According to the book, Harry was informed by a palace aide during a trip to Toronto that a tabloid was gearing up to reveal his secret relationship with Markle. Several aides from the palace urged the prince to come home, pointing out his minimal security. However, he allegedly refused.

Markle was allegedly disappointed the relationship was leaked by the press but also was “relieved not to have to keep lying to friends about her trips to London.” It is said that while Harry warned Markle word would get out, she was still surprised by the intense media scrutiny.

According to the book, a photographer waited for Markle by her car. She spotted him and called the police. “This is how it’s always going to be, isn’t it?” she then told a friend.

While it was initially reported that Harry and Markle cooperated with the authors, reps for the couple confirmed to Fox News on Saturday that they played no part in the upcoming tell-all.

MEGHAN MARKLE HAS FREEDOM TO SPEAK ‘FROM THE HEART,’ ISN’T BOUND BY ‘CONSTRAINTS’ OF ROYAL LIFE: AUTHOR

“The Duke and Duchess of Sussex were not interviewed and did not contribute to ‘Finding Freedom,’” reps said in a statement. “This book is based on the authors’ own experiences as members of the royal press corps and their own independent reporting.”

According to the book’s description, “Finding Freedom” aims to set the record straight about the royal couple.

“For the very first time, ‘Finding Freedom’ goes beyond the headlines to reveal unknown details of Harry and Meghan’s life together, dispelling the many rumors and misconceptions that plague the couple on both sides of the pond,” read the book's description. “As members of the select group of reporters that cover the British Royal Family and their engagements, Omid Scobie and Carolyn Durand have witnessed the young couple’s lives as few outsiders can.”

“With unique access and written with the participation of those closest to the couple, ‘Finding Freedom’ is an honest, up-close, and disarming portrait of a confident, influential, and forward-thinking couple who are unafraid to break with tradition, determined to create a new path away from the spotlight, and dedicate to building a humanitarian legacy that will make a profound difference in the world,” the description added.
