What would you say if you were told: "Hey! Someone's discovered the fountain of youth!"? You'd say: "Olay, Schmolay, that's amazing!" And what would you say if you were then told: "And the person who has discovered it is David Copperfield"? You'd say: "So what happened on 'Enders last night?"

OK!, to its eternal credit, does not do that while interviewing magician – or, to use his professional title, ex-boyfriend-of-Claudia-Schiffer – David on one of his four islands. LiS had no idea that saying "ta dah!" was so lucrative.

Incredibly, Copperfield Bay has more to offer than just "coconuts with speakers in them", a high-end concept I last saw in a Tahitian bar in Leicester Square (it was a loo emergency). "I discovered something amazing, which has caused a lot of controversy – the fountain of youth," whispers David. "I have to keep it a secret!" He then fulfils this by telling OK! readers he has "been able to take dry leaves and watch them come alive again, small animals, too".

There is certainly something miraculous going on with his hair, which seems to be washed in the same youth-bestowing lacquer favoured by Paul McCartney. Just For Men, Fountain of Youth, six of one, half a dozen of the other, right, David?
