With him singing a song for his upcoming film Special Chabbis, Akshay Kumar has turned a singer. And in a gesture of sorts, he has dedicated the song to his wife Twinkle Khanna. The actor-producer sang the song '<em>Mujme Tu</em>...' in front of the media yesterday during the music launch of the film at a cinema hall in South Mumbai. Apparently, this is the same song for which he had rehearsed but, unfortunately, it was not used in the film. Incidentally, Akshay had reportedly sung a few lines of a song from his 2010 comedy <em>Khatta Meetha</em>.
