John Mayer Dedicates Song To Katy Perry At Concert

John Mayer kicked off his Born and Raised World Tour at the Marcus Amphitheatre in Milwaukee, Wisconsin on Saturday night, an the singer gave lady love Katy Perry a sweet shout out while performing "A Face to Call Home," telling the crowd that Katy is "my face to call home." Of course, Katy was watching from onstage!

In a recent interview with Rolling Stone, Mayer credits Perry for sticking by his side when he suffered vocal chord problems that left him unable to sing or speak for about 20 months. "She was so patient," he said, adding that she took the time "to continue to get know me and love me" despite the vocal impairment.

The lovebirds first started dating in the summer of 2012, they broke up that August and then they got back together again in September, only to split again in March. The couple's romance heated back up later this spring when John attended a Memorial Day bash at Katy's new Hollywood Hills home.
