The latest royal rumor swirling around is that Prince William allegedly had an affair on his wife, Kate Middleton, with her friend, Rose Hanbury, and that that’s why there’s a supposed rift between the two women.

It all started when The Sun alleged that Middleton and Hanbury were no longer friends, leaving readers to speculate about what happened between them. In Touch claimed the reason for the falling out was because Prince William allegedly cheated on the Duchess of Cambridge with Hanbury.

The magazine’s source said Middleton “immediately confronted” her husband about it all, and he “just laughed it off saying there was nothing to it,” according to The Daily Beast.

Fans of the royal family already know a lot about the Duke and Duchess of Cambridge, but who exactly is Rose Hanbury? Here are 11 things to know about Prince William’s alleged mistress:

1. Her full name is Sarah Rose Hanbury, but she goes by Rose Hanbury.

4. The couple has three children —twin sons, Alexander and Oliver, and a daughter, Iris.

5. Her title is Marchioness of Cholmondeley, which means she’s the wife of someone who’s a marquess. Marquess is the title right below a duke.
