Sir Elton John's husband David Furnish has put him on a strict diet to help him lose weight.
The Sacrifice hitmaker has piled on the pounds lately and Furnish is determined to help him adopt a healthier lifestyle.
He says, "I can't change him but I want him to be as fit and physically and mentally sound as he can be.
"The message has gone out to the people on the road: no bowls of M&Ms in the dressing room. I don't want nacho chips lying around. And he's drinking water now rather than Diet Coke."
Sir Elton John's husband David Furnish is devastated at the prospect of never having kids, blaming the superstar's busy workload for denying him the chance of fatherhood.
The pair, who married in a civil ceremony in 2005, had always dreamt of raising a family together.
But now Furnish concedes this is never likely to happen -- because Elton's always too busy.
He says, "I wanted children. We talked extensively about adopting, but it came down to Elton saying, 'I'm going to continue to do what I do and it will be very difficult to raise a child with you if I'm not going to be there'."
Furnish, 45, fears he will always be sad about the decision.
He adds, "It will be my one regret when I leave this planet; that I never had children of my own, because I really love children."
