They've been dating for the last few months, but it looks like Katy Perry and John Mayer have finally made it official with the 'Firework' star calling the rocker her “boyfriend” at a recent event in New York.
It was the first time the couple have taken their romance public following months of speculation and looked pretty loved up up on the red carpet for a performance of 'A Christmas Story: The Musical'.
They even took John's father along to the event – now that means it's serious!

According to Us Weekly, despite his lothario reputation Mayer was a perfect gentleman, with Katy introducing him as her boyfriend, an eyewitness said: "You would think he was just a supportive boyfriend,"
"He let her be the star."
Despite claims of a split in September the pair looked more loved up than ever and it seems Mayer has finally turned over a new leaf and is ready to settle down.
The insider added: "John has always thought Katy was really sexy," "He loves curvy girls."
