The aliases of Vladimir Putin's alleged secret sons have been revealed as new video footage and photos of the boys appear to show that they're being prepared to become athletes like their Olympian mom. Putin is believed to have fathered two sons, Ivan, 10, and Vladimir Jr., 6, with former Olympic rhythmic gymnast Alina Kabaeva, who was once hailed as “Russia’s most flexible woman.” A video obtained and newly published by OSINT Bees appears to show Ivan being interviewed and speaking about “cool” gymnastics moves he learned from Olympic champions Alexei Nemov, Evgenia Kanaeva and Taghir Khaibulaev.
