Kate Middleton is the queen of maternity style!
The Duchess of Cambridge made her third appearance since her pregnancy news at an "Action on Addiction" dinner in London on Thursday.
The glowing mama-to-be looked radiant in a woven, black knee-length Temperley London dress, which she paired with a black beaded clutch and her favorite suede pumps.
Kate debuted her teeny, tiny baby bump as she joined her husband Prince William to greet The President of the Republic of Singapore and his wife Mary at London's Royal Garden Hotel on Tuesday.

Earlier this week, Kensington Palace confirmed that the royal couple will welcome their second child in April, 2015.
Kate has suffered from hyperemesis gravidarum, a serious form of morning sickness, for the first three months of her pregnancy. After canceling a series of royal events, we're happy to see that Prince George's mama is on the mend!
