I can't swear that it is real but I do remember him being asked outright on another programme some time ago.
His reply was that every 8-10 weeks he and wifey head off to the sun for a week or so.
Obviously he is easily wealthy enough to do that if he wishes. Seems like a high risk of skin cancer to me.
There was a programme some time ago ..I think it was one of tracing your ancestors things ..who do you think you are ? Something like that and he traced his relatives back to Istanbul .He was an adopted child .They interviewed him with his wife ( who I think used to be a singer ) and he was really sweet .
I have never had a tan. :-( Tried some bottle stuff once and had to hide for a week. Low boredom threshold. Did one leg and thought..hell, life`s too short for this and left the other.
