How Katy Perry Surprised Fans at John Mayer Concert

Yahoo Celebrity

Katy Perry and John Mayer seem like the perfect couple, and it definitely showed when the "Roar" songstress made a surprise appearance at Mayer's concert at the Barclay Center in Brooklyn, New York, Tuesday night.

Joining her boyfriend on stage for a duet of "Love Who You Love," it was obvious that the couple really has an insane amount of chemistry.

"Someone I know we all love – me a little more than you – please welcome the fantastic Ms. Katy Perry," Mayer told the crowd before his girlfriend walked out.

Upon hitting the stage, Katy was greeted with a ton of applause. The lovebirds also shared a sweet kiss before belting out their new hit song.

After an end embrace, Perry went backstage and reappeared with her handsome man and his band for their final bow.

The Hollywood power couple has been making the rounds to promote their duet, making an appearance together on "Good Morning America" Tuesday and debuting their sensual music video for the single later that same day.

Check out this video to see how true their song really is, and tune in to "omg! Insider" on TV tonight for more of the latest in entertainment news!
