EXCLUSIVE: Diddy and the escort girl he paid for by cutting the ribbon on her new pet shop! A hilarious interview with legendary DJ David Hamilton… and the second wife who saved him from bachelordom worthy of a Carry On film

Well, this could be awkward. It was Mrs ‘Diddy’ David Hamilton — the legendary DJ’s second wife — who suggested that I conduct this interview with her husband out on the patio, by the swimming pool.

She leaves us alone, as you would probably do too, if you knew your husband was going to be talking to a national newspaper about all the women he has loved and lost, and — ye gods! — paid for sex with. Diddy and I have been chatting for an hour by the time Dreena trots out to join us, bringing more tea.

This explosive new book, warns its author, is “not for the fainthearted. It does contain sex, drugs and rock ‘n’ roll – though not necessarily at the same time.” Are these fresh revelations from Mick Jagger or Ozzy Osbourne? Astonishingly, no: it’s a tell-all shocker from the veteran presenter David Hamilton (aka “Diddy David Hamilton”), the beloved voice of BBC Radio 1 and 2 and Boom Radio.

That juicy caution was shared on Facebook yesterday to members of his devoted fan club, David Hamilton’s Hot Shots, but it doesn’t begin to prepare potential readers for the eye-watering revelations in his sixth book, David Hamilton’s Long and Winding Road, which is published on July 19. As the group’s admin Noel Tyrrel observes, Hamilton seems to have abandoned the maxim “a gentleman never tells”. It certainly casts this respected titan of the golden age of radio in a very different light.

The blurb for the book teases frank tales of working with comedy legends such as Ken Dodd, Tommy Cooper and Benny Hill, and mentions that Hamilton, 85, writes about “the beautiful women he has loved”. By that, you might expect fond recollections of courting his two wives: Sheila and Dreena (with whom he shares five children and nine grandchildren).

In fact, this unlikely lothario spills the beans on his extraordinary secret love life – which includes a fling with a prostitute. Hamilton shares with readers how his affair with BBC co-presenter Roz Early broke up his marriage to his first wife Sheila in 1970, and that following the split he went on to have relationships with model Kathy McKinnon, the daughter of a judge, and then – astoundingly – with a sex worker he names as Melanie or Mel.
