Kate Middleton is rumored to be pregnant with baby number four. And just like her first three pregnancies, the Duchess of Cambridge is still waiting for the perfect time to share the news to the entire world.

Bookmakers Ladbrokes slashed the odds of Prince William and Middleton to having a baby next year to 6/1. The bookmakers also said claimed that a pregnancy announcement will be made before the year ends.

Since there are only three weeks before 2019 wraps up, royal fans are waiting to see whether the bookmakers’ predictions are correct.

“Is she or isn’t she preggy? I’ll be happy if she is… Crossing my fingers that she’ll have twins – a double treat,” Twitter user @bernadette_07 wrote.

“Me too! I think she is! There are rumors that she’s pregnant, because the Royal Dr. is with them in Pakistan visit! She’s glowing! I hope it’s true! I think it’s true! I can’t wait!” Twitter user @MemarpouriM wrote.

While speaking with Express, royal commentator Richard Fitzwilliams also weighed in on the rumors subtly. He said that royal fans are convinced that the Duchess of Cambridge is once again expecting after she attended the Royal Variety Performance.

The last time that Prince William’s wife attended the event was in 2017 while she was pregnant with Prince Louis.

And just this week, Katharine Graves, the author of “The Hypnobirthing Book” told Express that Middleton could be announcing her fourth pregnancy fairly soon. She said that the age gap between the future Queen’s children is a telling sign.

“Two years between George and Charlotte and three years between Charlotte and Louis. On that basis, we could expect a fourth little Cambridge to be on the way fairly soon. When you live in a goldfish bowl as the royal children do, it must be thoroughly healthy to have siblings to grow up with,” she said.
