If Prince Harry mentions her in his future memoir, Cressida Bonas, Prince Harry’s ex-girlfriend, could react by penning the first book on their relationship.

Bonas was “shocked” to learn of the Duke of Sussex’s decision to write an explosive memoir about his life, according to the Daily Mail.

A friend told the tabloid that she, too, could be “tempted to write about [the relationship] now.”

“She could give a different perspective on the relationship,” said the source.

Daniela Elser, a royal observer, also weighed in on the idea of Bonas writing about Harry.

“While the chances of this coming to pass are slim, given Cressida has been nothing but impressively discrete about her Harry romance, the very fact that this question is even being publicly pondered for the first time is noteworthy,” Elser wrote in a piece penned for News.au.com.

“Just in case the possibility of his former friends becoming loose-lipped isn’t enough of a worry, Harry’s tell-all could also potentially see royal aides given the green light to hit back and to publicly talk about experiences working with Harry and Meghan,” she added.
