In the clip, President Ramaphosa takes pictures of Zozibini and Siya on a cell phone, adding that he is "delighted" that they were able to attend.
Later, the president joins the pair for another photo, saying: "Zozi we were watching you. At 3 am, we watched you. We watched you as you were crowned."
"But I didn't only watch Siya, I was there when he lifted the cup," Ramaphosa jokes, adding: "We are so proud."
