The Duke and Duchess of Cambridge joined industry leaders from across the country at Buckingham Palace for World Mental Health Day.
For the occasion, The Duchess, who has been suffering from Hyperemesis Gravidarum (a severe form of morning sickness which she also had with Prince George and Princess Charlotte), wore a pale blue lace dress by Temperley London (which is still available to shop) and black stilettos, paired with a black clutch.
If you look closely, you can see The Duchess is displaying a small baby bump.
For her third pregnancy, Kate is reportedly considering breaking royal protocol to have a home birth. Thanks to a statement by excited dad Prince William, we're guessing the new royal baby is due in March.
