Both Maria and Katerina are believed to be Putin's daughters with his former wife Lyudmila Putina, though their identities are an open secret in Russia. Putin is also suspected to have a third daughter Luiza Rozova from an alleged extra-marital relationship. While Putin's eldest daughter Maria Vorontsova is known to be a pediatric endocrinologist, his younger daughter Katerina Tikhonova is a scientist and former acrobatic dancer. She is also the ex-wife of Kirill Shamalov, a prominent Russian businessman who was sanctioned by the US recently.
