Duchess Kate Middleton Plays with Prince George & Princess Charlotte in Cute Photos!

Catherine, Duchess of Cambridge (aka Kate Middleton) looks like such a doting mom while playing with Prince George, 4, and Princess Charlotte, 3, during the Maserati Royal Charity Polo Trophy at Beaufort Park on Sunday (June 10) in Gloucester, England.

Husband and dad Prince William was competing in the event that day, and the whole family, minus baby Prince Louis, was in attendance to cheer him on!

At one point, Duchess Kate was seen running around with the kids, and later on, the young Prince and Princess ran around and chased each other!
