Russian president Vladimir Putin, 65, has tried to keep his personal life almost entirely out of the spotlight.
From his first marriage of 30 years to reports of a girlfriend, Putin and his administration have fought hard to prevent the media and the world from knowing much about him - aside from the carefully curated macho man on horseback, lifting weights and posing in shirtless photos.
He has specifically made a concerted effort to shield his children from any spotlight, prompting many to even question whether he has any kids at all.
Rumors have swirled for years that Putin has two daughters with his ex-wife, and that his reported girlfriend may have had another daughter in 2015.
Here is what we know about the mysterious lives of Putin's secret kids.
