However, the Mabuse sisters have another third middle sibling, who is said to be the best dancer of the three.
Phemelo Mabuse, 35, is an MBA graduate who works as a mechanical engineer, building windmills in their native South Africa.
While her sisters are widely known for their dancing skills, Phemelo is said to be the best, MyLondon reports.
Speaking on the Jonathan Ross show recently, Oti revealed: "To be honest, we have another sister - middle sister - she was the better dancer.
"She's a mechanical engineer. She designs windmills which create electricity through wind in South Africa."
While juggling her engineering work, Phemelo has stayed involved in the dancing world and teaches dance in Pretoria and Johannesburg.
She also won the Latin American & Ballroom in the Juvenile, Junior and Youth categories and also represented South Africa four times at the World Dance Sport Championships.
