Yes you read it right. But wait, he became the Best man, and not in real life for his upcoming song, "Mera Jahan". The song is about the love story between Gajendra and Kritika, but due to some reasons they can't get married. SO, just to make sure she remains happy, he becomes her best man on her wedding day.
Rest i think you should listen the song, and get with the flow. You surely will love his voice and the video dipction.
