Sir Elton John still financially supports the young boy he tried to adopt.
The 68-year-old musician and his husband David Furnish, 53, were charmed by Lev, who they met in a Ukrainian orphanage in 2009, and although they were unsuccessful in their adoption attempt, they managed to unite him with his grandmother and now support them both.
He told Rolling Stone magazine: "We got him to the grandmother, and we surreptitiously look after them."
Elton also revealed that Lev inspired him and David to have their own children, leading to Zachary and Elijah being born via a surrogate in 2010 and 2013 respectively.
He explained: "I always said no to having kids, because I'm too old, too set in my ways, too selfish, the lifestyle doesn't suit me. But I said, 'This boy we met was trying to tell me something.' He was trying to say, through God or someone else, 'Bulls**t, you can be a dad, look at how much pleasure I gave you in an hour and a half.'
"And I said, 'Let's go for it.' God, that was the best decision."
Meanwhile, Elton also praised his "darling David for weeding out all the horrible people in my life".
He added: "David came into my life, and in the last two years has been very involved in sorting out the dross that we had surrounding me. We had so many people who were earning vast amounts of money that weren't pulling their weight.
"Every year at this time, we've been looking for money to pay our taxes, but this year we've already got the money.
"David doesn't mind being Yoko Ono, but he's doing it on my behalf."
