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.

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.
