Meghan Markle is one of the kindest souls a person could ever meet, according to her childhood friends.

As Prince Harry and Markle's royal wedding approaches, more and more people are becoming interested in the "Suits" actress and her past. Now, a new book, titled "American Princess: The Love Story of Meghan Markle and Prince Harry," by Leslie Carroll delves into Markle and her fiancé's past.

Catherine Knight, who knew the future royal back in middle school as they both attended Immaculate Heart, said that Markle is "kind, generous and enthusiastic," Express, who got a copy of the book, reported. Another friend described Prince Harry's bride-to-be as "bubbly, optimistic and positive."

"Harry is lucky to have her," another classmate said. "No one who knows Meghan could have a bad word to say about her. She is the kindest person and incredibly smart. She doesn't buy into Hollywood fakeness."

Gigi Perreau, Markle's drama teacher, had always known that she "would be something special." "A lovely girl even then, and very hardworking. [Meghan] was very dedicated," Perreau said.

This is the second book about Markle released this year. Andrew Morton also wrote a biography about Prince Harry's fiancée titled "Meghan: A Hollywood Princess."

In his book, Morton claimed that Markle was obsessed with Princess Diana. In fact, she reportedly cried when the late Princess of Wales died.

"Meghan and her friends watched the funeral of Diana, Princess of Wales, in early September 1997, tears coursing down their cheeks at the poignant moment when the cameras zoomed in on the royal coffin," Morton wrote.

The royal biographer also revealed that the actress and Prince Harry clicked right away and that they could be distant cousins because the "Horrible Bosses" star is a descendant of Scottish warlord Robert the Bruce.

The book also covered Markle's previous marriage with Trevor Engelson. According to the people that Morton talked to, their relationship started strong, but the "Suits" star ended it out of the blue.

"A wealthy entrepreneur friend claimed the marriage ended so abruptly that Meghan sent her wedding and engagement rings back to Trevor by registered post," Morton wrote. "Another confirmed that the decision to end the marriage was made by Meghan and that it had come 'totally out of the blue.'"

Markle's childhood best friend, Ninaki Priddy, admitted that she felt bad about the actress' decision. It eventually caused the rift in their friendship.

"What came to light after Trevor and I spoke ended my friendship with Meghan. I think everybody who knew them both was in shock," Priddy said. "All I can say now is that I think Meghan was calculated, very calculated, in the way she handled people and relationships. She is very strategic in the way she cultivates circles of friends."
