It took six months and a breakup or two, but Katy Perry and John Mayer appear to be getting comfortable in the public eye. On Thursday night, the pair cozied up at a Rolling Stones concert in New Jersey, where Mayer joined the veteran rockers onstage for a song.
While watching the band, Katy and John stayed close and exchanged smiles, and he was seen talking into her ear (imagined question: "Do you still have the bra that shoots whipped cream?").
Their understated PDA follows a similar outing the night before, when they were photographed at the Broadway production of "A Christmas Story: The Musical." In another sign of their growing comfort level as a couple, Mayer's dad joined them for dinner and the show.
According to Us, Perry happily introduced Mayer to the "Christmas Story" cast, announcing, "This is my boyfriend, John."
It was also apparently her idea to document the moment for the posterity by posing together. "Come on, baby, let's take a picture," Katy reportedly told the crooner.
"You would think he was just a supportive boyfriend," a spy tells the mag of Mayer hanging back while Perry bonded backstage with the child actors. "He let her be the star."
