The star and her hubby, Tshepo Gavu, hosted a cute reveal party for family and friends last month, just days after taking to social media to announce their pregnancy.
“After a really beautiful, chilly, emotional, fun, joyful day filled with love. Having prediction after prediction, the family going it's a girl, it's a boy. We popped the balloon and ... Mommy wins, it's a boy!”
The pair got married in February.
