KATE Middleton joined the Queen this Easter Sunday for a service at Windsor Castle in what could be one of her final public appearances before giving birth. The heavily-pregnant duchess, set to give birth to her third child in a matter of weeks, appeared alongside Prince William and a host of royals for the service. However the couple were without Prince George and Princess Charlotte at St George’s Chapel, which is where Prince Harry will wed Meghan Markle in May. On March 22 Kate made her final public engagement before giving birth. A Kensington Palace spokeswoman said: “Today’s public engagements by the Duke and Duchess of Cambridge will be Her Royal Highness’s last before starting her maternity leave.” Today however offers the public a chance to glimpse at the Duchess perhaps for a final time before she goes into labour. In recent weeks she has been busy appearing at charity events and was also seen alongside Harry and Meghan. But after today she is expected to wind down from official engagements and prepare fully for giving birth. She was seen dressed in all black and greeting church officials and fellow worshippers before making her way inside. We pay for your stories! Do you have a story for The Sun Online news team?
