Ms Hay, who attended high school with the Duchess, has spilled the baby-beans to New Idea, telling the magazine that a little sibling is on the way for little Prince George.
“Kate’s inner circle are buzzing with the news that she is pregnant,” Hay told the glossy. “I’ve heard it from several different friends of theirs now and they’re saying that they think there’s going to be an official announcement in weeks.”
And how does the “oldest friend” of the Duchess and the unofficial mouthpiece for the royal pair know this tabloid titbit?
“(Kate) has rosy cheeks, she’s letting her greys show again and whenever she’s out in public she goes to great lengths to hold something over her tummy,” Ms Hay says.
Better than any doctor’s exam right?
Hay famously predicted the couple’s first pregnancy weeks before the official announcement but her credibility has also been tested.
Apart from not being seen with the Duchess for several years, Hay has previously spilled on Kate’s private life, dribbling the secrets of the young royals dating life to the press and claiming Kate was a victim of school yard bullying – a story she later retracted.
Only time will tell if Kate’s blabbering friend is telling the truth but in the meantime we think the Queen might be ready to get her pack of corgis onto royal secret spilling spies?
