The birth certificate was issued by the Chertanovo civil registry office in Moscow on July 10, 2026, almost 11 months after the birth, Agentstvo reported, citing the leaked records. Under Russian law a child must be registered within one month.
The first birth document was issued on the day of the birth by the Central Clinical Hospital of the Presidential Administration's property department.
The child was registered as Adrian Igorevich Tikhonov. The patronymic matches the first name of the presumed father, choreographer Igor Zelensky, with whom Tikhonova is in a relationship. The boy was given his mother's surname rather than that of his likely father.
Agentstvo suggested the delay in registration may be linked to the family's wish to conceal the birth, or to complications arising from the parents having different surnames. The exact reason was not given.
Tikhonova and Zelensky already have a daughter together, Elza, born in 2017. Her existence was previously reported by the outlet Proekt.
Tikhonova was married to businessman Kirill Shamalov from 2013. News of their divorce emerged in January 2018, the same period in which her relationship with Zelensky began; at the time he was artistic director of the Bavarian State Ballet in Munich.
Putin himself has mentioned two grandchildren, children of his elder daughter Maria Vorontsova. One of them was fathered by Dutch businessman Jorrit Faassen, to whom Vorontsova was married, and the other by Novatek manager Yevgeny Nagorny.
According to journalists, Putin also has children with former gymnast Alina Kabaeva. The president has not mentioned them.
