It's officially official!
The two singers recently attended "A Christmas Story, The Musical" in NYC together, where they took photos with the cast and even met Santa.
According to Us Weekly, Katy introduced John to the children, and proudly told them: "This is my boyfriend John."
A witness recalls Katy acknowledging John as her "baby" when asking to take a picture with the kids: "Come on, baby, let's take a picture."
John must really like Katy, since he let her take in all the attention when they were hanging out backstage with the whole cast.
An insider told the magazine:
"You would think he was just a supportive boyfriend."
Maybe being able to show how official they are to their fans is John's Christmas gift to Katy!
