- Kate Middleton showed off her growing royal bump while attending a charity dinner at Kensington Palace.
- True to Kate's knack for repeating outfits, she donned a black floor-length gown that she's worn twice before.
- Kate had been suffering from an extreme form of morning sickness earlier in her pregnancy, but she was absolutely glowing at the gala.
- Kate and Prince William are expecting their third child in April 2018.
Kate, who is expecting her and William's third royal baby in spring next year, was seen with an ever-so-slight bump at the mental health charity night at Kensington Palace.
The palace announced the pregnancy in early September and the following month confirmed the new baby will be due in April.
The Queen was said to be "delighted" by the Duke and Duchess' happy news.
On Tuesday night, Kate appeared in a black floor-length dress as she arrived at the palace's 18th century Orangery reception rooms.
The Duchess met supporters and those who have been helped by the Anna Freud National Centre for Children and Families (AFNCCF) at a reception ahead of the event, held to celebrate the charity's work.
As with her previous two pregnancies, Kate had been suffering an extreme form of morning sickness known as hyperemesis gravidarum.
Betting has already begun for the name of the new member of the royal family, with Alice, Arthur and Victoria highlighted as big favourites among bookmakers.
The names Albert, Henry and Elizabeth are also all ranking highly.
