Their union has given birth to a love song Mafokate calls "a guaranteed hit".
According to SW, Khumalo provided the lyrics to the love song, called ‘Nguwe Lo’ (You Are the One), and they performed it for the first time yesterday at the Can Do Refresh Tour in Bloemfontein.
However, Mafokate said he is not ready to walk down the aisle as a husband in the music video, which will be shot next week.
"I'm scared. I will get someone else to play the role of the groom in the video," he told the newspaper.
"I wanted the same effect I had when I collaborated with the late Lebo Mathosa on the song Oyi Oyi. It was magical and people loved it. I don't know what dance moves we will invent yet."
Mafokate said he admires Kelly because she has a strong character and he continued to say: “What people don't know is that she is talented musically. She has become known for her private life rather than for her music. I would like to make the relationship last longer and manage her to become one of the best musicians this continent has seen.”
