The Duchess is nearly eight months pregnant

Kate Middleton is set to celebrate the 60th anniversary of the Queen‘s coronation with members of the Royal Family next week.

The Duchess of Cambridge, 31, will be almost eight months pregnant at the service in London’s Westminster Abbey on Tuesday.

It’s thought to be one of her final public appearances before she gives birth to her and Prince William‘s first child together, which is due in July.

Her last official engagement is believed to be the naming of a Princess Cruise ship in Southampton on 13 June.

Prime Minister David Cameron will speak at the Queen‘s milestone ceremony.

It will be lead by the Dean of Westminster and the Archbishop of Canterbury will give the address.
