Katy Perry has introduced John Mayer as her "boyfriend", sparking speculation that they are officially a couple.
The Grammy-winning Teenage Dream songstress and the 35-year-old musician attended the Broadway adaptation of the classic 1983 film A Christmas Story in New York City with John's father Richard, reported US Weekly.
It is claimed Katy said: "This is my boyfriend John," when introducing him to the cast.
When the couple posed for photos with the group, Katy called him over, saying: "Come on, baby, let's take a picture," an eyewitness told the magazine.
Katy, whose divorce from British funnyman Russell Brand was finalised in July, was first spotted with John in June. The couple, who reportedly split briefly in August, rekindled their romance in September.
