The couple welcomed their first child together on Wednesday.
Mayihlome Tshwete announced the arrival of his son with Zizo by uploading an image from the Lion King and captioning it: "It's a baby boy."
The pair wed in a beautiful ceremony attended by high profile guests last December. A heavily pregnant Zizo looked stunning in her gown.
The two had previously declined to confirm their relationship but have become more open about it, sharing images together on social media.
Mayihlome posted a pic of him wearing medical booties as he waited for the arrival of his child.
The doting dad has been so excited for the birth of his little one that he has been sharing snaps of him shopping for baby goodies.
