The pair has reportedly been dating on and off since the summer, but they have stayed away from public events. However, they appeared to confirm rumours of a blossoming romance by walking the red carpet together at a showing of A Christmas Story: The Musical at Manhattan's Lunt-Fontanne Theatre. Perry and Mayer met the festive production's young cast and happily posed for pictures with the show's composers, Benj Pasek and Justin Paul. The I Kissed A Girl hitmaker also posed with a Santa Claus impersonator at the event. You May Also Like Babing guys and cute animals (Warning: HOT!)
