The duchess told the proud father: “He’s gorgeous. It makes me feel a little broody.”
Now back in Ireland to celebrate St Patrick's day, Kate was non-stop smiling alongside husband Prince William, with many attributing her 'glowing' demeanour to the continued speculation of another royal baby.
According to Honey9, Ladbrokes had taken bets that William and Kate are expecting baby number four, which as all royal fans would know, is always a fairly solid indication at the way royal events are going to arise.
Whilst some royalists are seeing kate's demeanour as more evidence to an impending pregnancy announcement, some pointed out that the Duchess of Cambridge did enjoy a sip of the traditional Irish stout, Guinness, on St Patricks Day, which would suggest that the royal may not be with child.
The royal couple already have a young family of three – their first child Prince George, daughter Princess Charlotte and their third child, Prince Louis.
It's all about babies right now within the British royal family, with pregnant Meghan Markle and Prince Harry currently expecting their first child.
