Kate Middleton stunned in a Temperley little black dress for the annual SportsAid charity dinner in London Thursday evening.
The Duchess of Cambridge paired the lace frock with a pair of Jimmy Choo pumps and a bright red clutch (complete with an adorable bow!).
Three of the charity's youngest talents as well as several lucky Olympian athletes greeted Middleton upon her arrival outside of Embankment Gardens.
The 31-year-old attended the event alone, leaving Prince William on babysitting duty for four-month-old Prince George.
Middleton has been a patron of the SportsAid charity for quite a while now.
In fact, in October, an appearance of her at one of the athlete workshops caused quite a stir.
Middleton was seen playing indoor volleyball with fellow charity workers at Queen Elizabeth Olympic Park in London and at one point flashed her washboard abs during the game.
Hayley Connor, a badminton coach for SportsAid, tweeted a picture of Middleton at the morning event. "Not your ordinary day - Met HRH the Duchess of Cambridge aka - Kate Middleton," she captioned. "What an amazing opportunity."
Middleton is an official patron of eight other charities, including 100 Women in Hedge Funds Philanthropic Initiatives, Action on Addiction, East Anglia Children's Hospices (EACH), National Portrait Gallery, Natural History Museum, The Art Room, The Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry, Place2Be and SportsAid.
