The Duke and Duchess hit up some horse racing.
A source tells E! News that the Duke and Duchess were very happy, smiling and enjoying the day at the races, noting that the two acted like any normal couple, interacting with others in their group.
During the sporting event, William found himself the victim of an ear tug by a pal, much to the amusement of Kate standing behind him.
And based on the photo seen here, the heir to the throne either didn't notice the playful pull or simply chose not to acknowledge it while watching the races.
Talk about concentration!
