Poisoned Kremlin critic Alexei Navalny continues to be a thorn in the side of Russian President Vladimir Putin after unearthing the Instagram account of the strongman’s purported 17-year-old love child, according to a report.

Putin, 68, has been linked by Russian outlet Proekt to Svetlana Krivonogikh, a cleaner who is worth more than $100 million and lives in a posh area of St. Petersburg.

Glamorous images of her luxury-loving daughter Elizaveta — also known as Luiza – have emerged online showing the teen sporting a Gucci mask, posing seductively in designer outfits and drinking booze amid the coronavirus pandemic, The Sun reported.

The teen’s Instagram account has been exposed by Navalny, who was taken into custody Sunday night after flying home for the first time since he was poisoned last summer, according to the news outlet.

Her postings reveal her love for top luxury brands including YSL, Bottega Veneta, Miu Miu, Tom Ford, Chanel, Jacquemus, Dolce & Gabbana, Valentino, Alexander Wang and Maison Margiela, The Sun reported.

A video on Luiza’s account shows her dancing with a Russian teen who attended a school in Surrey, England, sparking rumors that she also was educated in the UK, according to the report.

The teen’s Instagram followers jumped from 17,000 to 42,000 in a matter of hours as she lashed out at her jealous “haters.”

“Wow, I can see a sweater paid for by my taxes. How many pensions does this sweater cost?” one user commented, The Sun reported.

“What do you say in school when they ask you: ‘Who is your father?’” another said.

Another offered the zinger: “What is it like to be born with Putin’s face?”

Luiza, who has reportedly been living under an assumed name for years, was born in 2003 while Putin was still married to now-ex Lyudmila Shkrebneva.

Proekt said her birth documents do not list a father, and only list “Vladimirovna” as the name deriving from her father.

Luiza’s mother, now 45, had been a cleaner from a modest background before becoming a beneficiary of a company that owns a small share in the Putin-linked Rossiya Bank, as well as owning properties in numerous cities, according to the Proekt probe.

She also owns a nightspot known for “erotic shows,” the report says, estimating her total assets as being at least $102 million.

Putin has never officially confirmed his two daughters from his first marriage — Maria and Katerina who are both in their 30s — and is widely rumored to have up to four kids with former gymnast Alina Kabaeva.

The latest revelation by Navalny comes after he alleged in a viral video that Putin owns an opulent billion-dollar palace that was built with fraudulently obtained funds.

The Kremlin promptly denied that Putin owns the palace.

Navalny was jailed for 30 days upon his return to Moscow in connection with alleged violations of a suspended prison sentence in an embezzlement case he insists was trumped up.

He fell into a coma while on a domestic flight from Siberia to Moscow on Aug. 20. Two days later, he was transferred from a hospital in Siberia to one in Berlin.

Labs in Germany, France and Sweden, and tests by the Organization for the Prohibition of Chemical Weapons, established that he was exposed to a Soviet-era nerve agent, Novichok.
