Another clue that the royal relationship might be inching forwards.
Cressida Bonas's brother has disclosed that he fears for her safety as her romance with Prince Harry gets increasingly serious.
Cressida's half-brother Jacobi Anstruther-Gough-Calthorpe (and you thought Cressida's name was silly) who works as a city investor by day and a DJ and house music producer by night, told the Evening Standard that he dislikes the media attention his sister is getting because they are a "private family".
"I'd rather the media machine didn't build around my sister," the 30-year-old said. "My only worry is making sure she is safe and she is ok and she is happy.
"I don't really think about it all except in the sense of her safety."
