Pharrell Williams rocked the iHeartRadio Jingle Ball hosted by Z100 at Madison Square Garden in New York City. After stripping off his long pink coat, he launched into his Robin Thicke collab "Blurred Lines" before he brought out Gwen Stefani to perform her new single, "Spark the Fire."

Pharrell closed out his iHeartRadio Jingle Ball performance with his smash hit "Happy" and decided to spread the happiness in New York City by inviting some fans on stage with him!

He even took some selfies with them!
