Russian world champion Alina Kabaeva performs with the ball during the World Rhythmic Gymnastics Championships in Madrid October 20, 2001.
Shortly after, he reportedly began dating Russian gymnast Alina Kabayeva, 32, who was born the same year he married Lyudmila.
According to Swiss broadcaster RSI News, Kabayeva and Putin are in Ticino, Switzerland because former Italian leader Silvio Berlusconi recommended the Swiss hospital of Sorengo.
"The Russian pair have reserved two rooms at the hospital of Sorengo, one for childbirth and a second for family and bodyguards. The rooms have been occupied for a few days, since the beginning of the week," RSI News reports.
The rumor stems from Putin's mysterious absence after canceling two meetings; one in Astana, the capital of Kazakhstan, and in Moscow with a delegation from the Georgian separatist region of South Ossetia, Reuters reports.
Putin has been out of sight for the last eight days and was last seen on March 5 with the Italian prime minister. Putin is to meet with the president of Kyrgyzstan early next week, the Associated Press reports, citing the Kremlin.
