Katy Perry and John Mayer enjoyed dinner and a musical with John's father in NYC last night. The trio went to eat at Sardi's before heading over to watch A Christmas Story: The Musical. Katy and John were full of holiday cheer as they took time to pose for photos with the cast, and even Santa Claus, following the show. It was one of the couple's first public appearances together after they started dating over the Summer.
Katy has been keeping busy this month, having honored Carole King in Hollywood last week before jetting off to Dubai for a short trip. That stamina might be a result of the good news about Katy's recent Grammy nomination, which she earned for best solo performance for her song "Wide Awake."
