Later in the event, Kate spoke to the crowd, congratulating them for the parts they've played in their children's success. 

"For all of you here, you go, and have gone, above and beyond the call of duty; you’ve committed your time and devotion to nurturing your children’s exceptional talents," she said. "And as a parent, I have a huge admiration for you and I know just how complex and time-consuming your role is."

Kate's been keeping very busy lately. On Tuesday night, she and her husband, Prince William, attended a charity performance of Dear Evan Hansen in London's West End. The couple are also set to take a three-day tour of Ireland in early March, coinciding with Prince Harry and Meghan Markle's return to the U.K.
