In part of Mastercard's "Priceless Surprises" Pharrell surprised one of his biggest fans, Queen.
The superstar showed up to a preschool where Queen was running a children's playgroup and literally danced his way into the room.
While she continued to dance to his song "Happy," you could see she was overcome with emotion as Pharrell took her hand and danced along to his Oscar-nominated hit (UMM can you imagine).
"This song was meant for people like yourself to keep you, keep me, keep them, keep us all going," Pharrell told her. "You're absolutely carrying a torch for the impetus of the record. And this is priceless what you do, the way you inspire these children, so thank you very much."
