Kate Middleton and Prince William made a sweet appearance together on Monday night. The couple, who is currently expecting their third child [1], was joined by Prince Harry as they made their way to Queen Elizabeth II and Prince Philip's 70th wedding anniversary [2] dinner at Windsor Castle. While the royal brothers looked dapper in their tuxes, it was Kate who really stole the spotlight. Aside from wearing a beautiful black lace dress, the duchess paid special tribute to the queen [3] by borrowing her pearl choker, which was also worn by Princess Diana [4] in 1982.

While Kate stayed out of the spotlight during the beginning of her third pregnancy, due to her severe hyperemesis gravidarum [5], she has slowly resumed her royal duties in recent months. Aside from giving us a glimpse of her growing belly during a charity gala [6] and honoring fallen soldiers on Remembrance Day [7], she also opened up about her children Prince George and Princess Charlotte while promoting children's mental health [8] at the annual Place2Be School Leaders Forum in London.
