Ms Alina Kabayeva, an Olympic gold medalist in rhythmic gymnastics, is believed to be the reason behind Russian President Vladimir Putin's alleged facelift.
British news website Daily Mail reported on Feb 27 that she is also purportedly the mother of at least one of his children. According to the New York Post, Ms Kabayeva gave birth to a son, Dmitry, in 2009.
In its detailed report, Daily Mail said that although she is rarely seen in public, Ms Kabayeva, 31, is regarded by many Russians as their country's undeclared First Lady.
Daily Mail also reported that in an effort to stay young, Mr Putin, 62, is said to take hot and cold baths after his gym sessions to hone his athletic figure. The article also alleged that he has had Botox in 2010.
The couple first came under the media spotlight in 2008 after a Russian newspaper, the Moskovsky Korrespondent, published a story linking the two of them.
In February 2014, wedding rings on the rumoured couple also renewed speculations of their relationship.
In September 2014, after a stint as an MP in Mr Putin's United Russia Party, Ms Kabayeva stood down and was made chairman of a major pro-Kremlin media group. Daily Mail also reported that at separate times, both parties have expressed love for unknown people.
Mr Putin's divorce from his wife Lyudmila Shkrebneva with whom he has two daughters, was finalised in April 2014. All claims of Mr Putin's relationship with Ms Kabayeva have been dismissed by his spokesman, Dmitry Peskov.
