Russian President Vladimir Putin, 69, doesn't seem to be happy with the news that his alleged lover Alina Kabaeva is expecting their child again.

The Russian leader is already thought to have at least two sons with the former Olympic rhythmic gymnast, reported Daily Star. The pregnancy news was first reported by Russian news channel General SVR Telegram. It said that Putin found out his "mistress is yet again pregnant and by the looks of it this wasn’t planned.”

Sources said that Putin was fuming when the news broke as he was tied up with preparations for the Red Square’s Victory Day parade, according to The Sun. After hearing his alleged lover was pregnant again, Putin was said to be "subdued and withdrawn." He was said to be particularly fearful that the news would tarnish the military parade amid his ongoing invasion of Ukraine.

Mirror reported earlier this week that the Kremlin leader flew to Sochi where she is believed to live. He reportedly went there around the time of Kabaeva's birthday, which falls on May 12. Putin recently toured the Sirius education centre in Sochi which was established the same year his first son was allegedly born. According to some reports, their first son was born in 2015 and another in 2019. Previously, it was reported that Kabaeva was hiding in Switzerland with their children.

Putin, who is rumored to be struggling with both cancer and Parkinson's disease, has never publicly admitted to having a sexual relationship with Kabaeva. The pair have been pictured together though. Rumors first linked the former gymnast romantically to the Russian leader as long ago as 2008.

Since rumors of their relationship began to circulate, she has rarely been seen in public. A source close to the former gymnast said regarding links to Putin that they "do not comment on the rumors." As for Putin, he previously said that he has a "private life in which I do not permit interference. It must be respected."

Kabaeva, who is fondly known as Russia’s most flexible woman, won bronze in all-around gymnastics at the 2000 Olympic Games in Sydney. Then she bagged a gold in the same category at the 2004 Athens games.
