Leading bookmaker Coral has slashed its odds on the royal couple announcing a fourth pregnancy before the year is out to odds on.
Coral's Harry Aitkenhead said: “We think that Will and Kate will add to their family in the next 18 months or so, so much so that we now make a pregnancy announcement during 2019 odds on."
In fact, Kate 37, recently gave a clue that she is thinking of having a fourth child, after meeting a five-month-old baby during a walkabout in Northern Ireland back in February.
“He’s gorgeous, it makes me feel broody," she told the baby’s father.
Furthermore, a source told the Daily Mail that behind closed doors, Kate is telling her inner circle that she’s ready for baby number four.
“She loves children and is prepared to put herself through another pregnancy even though they have been complicated by severe morning sickness in the past."
