Spencer Matthews has admitting to pulling a prostitute in just 25 seconds.
The star of hit reality show 'Made in Chelsea' was in Johannesburg, South Africa at the time, and bet his friend over who could pull a female in the fastest time.
Thinking his luck was in, he smooth talked a woman in the bar in under a minute, only to feel cheated when she demanded 100 rand (£6.20) for sex.
Speaking to The Sun newspaper about the revelation which he makes in his new book 'Confessions Of A Chelsea Boy', he said: "I felt as though I had been taken for a ride. We were having a juvenile contest to see who could pull the fastest and this girl came over and was really full-on.
"She was like, 'Do you have a hotel room?' When I said yeah, she was like, 'Let's go up'.
"I was so annoyed by the fact I had been tricked.
"Obviously it was sex so I wasn't that angry but I felt a bit hard done by."
The 25-year-old lothario also admits to once taking Class A drug LSD at a country rave, but claims he didn't know what it was at the time and wouldn't ever indulge in the substance again.
He added: "A tall, ginger, bearded gentleman offered up this drug, which I had never actually seen before.
"He looked like he was having a good time and I was spending some time with him and he said, 'Do you want to be on my level?'
"I didn't really know what he meant and he put some liquid on my hands. He told me to lick it. All sorts of hallucinations occurred and it was really quite uncomfortable.
"It's not something I would wish on anyone really. It's the last thing I would want to do again."
Spencer spent a lot of his younger years on the idyllic island resort of St Barts - where his parents own the luxury Eden Rock hotel - but it wasn't all fun in the sun on the heavenly land mass and he recalls one incident when he had to retreat to his hotel room because the son of former Libyan leader Colonel Gaddafi wanted him dead.
He explained: "I know he wanted to kill me and I know he could have, so that was scary when he was trying to knock my door down.
"There was a lot of banging on doors, people were being woken up and I was about as frightened as I'd ever been."
