An investigation conducted by Russia's Proekt claims President Vladimir Putin may be the father of a secret lovechild with one of his cleaners.

The report alleges the teenager is being hidden from the public by Putin.

Journalists said Putin may have conceived a child with a woman named Svetlana Krivonogikh - who now lives in an elite area in St. Petersburg reserved for Putin's closest friends and political allies.

The two allegedly had a daughter, Elizaveta Krivonogikh. She is 17-years old. One investigator said the teenager bears a "phenomenal resemblance" to Putin.

Facial recognition experts corroborated the claim saying that there is a 70% resemblance between Putin and the teenager.

"From this information, we can draw the conclusion that they may be related," the head of the Center for Visual Computing at the University of Bradford in the UK said.

Elizaveta was born in 2003 when Putin was still married to his now ex-wife Lyudmila Shkrebneva. During that time Elizaveta's mother was working as a cleaner for Putin.

The report said that Elizaveta's birth certificate didn't list the full name of her father but the name "Vladimirovna." Proekt said Elizaveta deleted all photos on social media after they attempted to contact her.

Elizaveta and her mother were reportedly given a small share in Rossiya Bank, a company that has been linked to Putin. The two reportedly also own several properties around the country and operate a nightclub named "Erotic Shows."

Investigators said that they had flight logs that showed both Elizaveta and Putin had flown together on several occasions. However, the two became estranged "somewhere near the end of the last decade," the report said.

Putin's representative denied the allegations and said it was the first they had heard of the name. Putin keeps his private life secret. The president has never mentioned two daughters from his first marriage. He is also rumored to have had children with former gymnast Alina Kabaeva.
