Motsi shares a daughter with her husband Evgenij Vozynuk, and the couple have chosen to keep their little girl's name a secret.
The BBC show judge recently had some more serious family drama, as her ex-husband sued her after claims she made in her autobiography.
She wrote that Timo Kulczak restricted her access to cash and controlled what she ate.
He has taken her to court for £70,000 and is demanding she retract the claims.
Motsi refused to settle, so will now need to prove her case before the judge in Germany.
