Athlete Caster Semenya and her wife Violet Raseboya are expecting their second born baby. 

The Olympic gold medalist took to her Instagram page to tease fans with a picture of her wife's all-grown bump.

Alongside their 2-year old Oratile, the couple was holding a baby's vest. 

"Ten little fingers, ten little toes. With love and grace, our family grows. This precious soul that God decided to bless us with. We all can’t wait to meet YOU!" Semenya wrote on her Instagram post. 

Fans flocked the comment section, congratulating the mothers-to-be.

Her wife Violet also posted the family picture with the same caption. 

Semenya married her long-term partner, Violet Raseboya, in December 2015 at a lowkey wedding.
