The Duchess of Cambridge visited the East Anglia Children's Hospice Appeal Launch Event in Norwich, England on Tuesday.
Sporting a quarter-sleeved red midi dress, the brunette beauty looked sophisticated yet stylish for the event. Middleton completed her look with black pumps and a chic ponytail.
News broke in September that Kate and Prince George were expecting their second child together.
"Their Royal Highnesses, The Duke and Duchess of Cambridge, are very pleased to announce that the Duchess of Cambridge is expecting their second child," Clarence House said in a statement. "The Queen and members of both families are delighted with the news."
The 32-year-old was treated for Hyperemesis Gravidarum at Kensignton Palace after the announcement -- the same disorder Kate suffered from during her first pregnancy with their son George.
It looks like Kate is feeling much better these days, though -- she's made numerous appearances over the last two months with her royal hubby.
We can't wait to find out the sex of their baby -- how do you think Middleton looks? Sound off below and check out the gallery above to see even more expecting stars!
