In a video of the surprise, Somizi looks shocked and confused, and then squeals in excitement when he realises what is going on.
The couple then share a kiss.
Earlier in the day, Somizi told Metro FM DJ Mo Flava that he was attracted to Mohale from the moment he met him.
“After our first date, I realised, damn, there are brains there, loads of brains. I am hugely attracted to intelligent people. So, for me, it was his brains and his drive.”
The couple also announced that they will be hosting a third wedding ceremony in Italy later this year.
