Russian leader Vladimir Putin is said to be getting ready to marry the Olympic medal winner gymnast Alina Kabaeva. Alina Kabaeva was born in Uzbekistan and her father is a Muslim Tatar.Here's Wikiepedia on Putin's Christian credentials:
Putin quietly divorced his wife Lyudmila Aleksandrovna. According to the claims, Kabaeva and Putin will get married in mid-June. Marat Kabaeva is a former professional football player. Marat Kabaeva warned his future son-in-law: 'my daughter is a very sensitive girl; so, know how to make her happy.'"
"Though his father was a "militant atheist", Putin's mother "was a devoted Orthodox believer". Though she kept no icons at home, she attended church regularly (despite the government's persecution of the Russian Orthodox Church at that time). She ensured that Putin was secretly christened as a baby, and she regularly took him to services. His father knew of this but turned a blind eye.
According to his own statements, his religious awakening followed the serious car crash of his wife in 1993, and was deepened by a life-threatening fire that burned down their dacha in August 1996. Right before an official visit to Israel his mother gave him his baptismal cross telling him to get it blessed â€œI did as she said and then put the cross around my neck. I have never taken it off since."
