During the Royally Obsessed podcast, Rachel Bowie and Roberta Fiorito discussed Princess Beatrice's being spotted with a pastel pink mask and rabbit during a dinner with friends in Mayfair. Ms Fiorito stated that it was "clear confirmation" that the Royal Family is set for another baby girl this year.
Ms Bowie said: "From Beatrice a possible accidental gender reveal.
"This past week she had a girls' dinner in Mayfair and she was holding a pink rabbit behind her back and she had a pink mask with a B and a crown on it."
Ms Fiorito replied: "I am totally convinced it is a girl, hands down.
"She tried to hide it and when you try to hide it, it is clear that is a confirmation, it has to be."

Ms Bowie interjected: "It was made for her mask because there was a B on it."
Ms Fiorito said: "It was pastel pink and the bunny was pastel pink.
"If it was not that then why would you hide it?
"I think we have just got confirmation it is a girl so I am super excited.
"Another royal girl for this year."
Ms Bowie added: "Yeah, the due date is this fall so it is coming up."
