JOHN Barrowman sensationally quit telly’s hardest reality show after less than 30 minutes.
The former Dancing On Ice judge walked out on Channel 4’s Celebrity SAS: Who Dares Wins during the first episode.
John, 56, had started filming in New Zealand with a raft of other famous faces including Rachel Johnson, Bianca Gascoigne and Anthony Ogogo last week when he threw in the towel.
A source said: “John’s exit from Celebrity SAS: Who Dares Wins will go down in the show’s history as the fastest ever.
“They’d all got kitted up in their uniforms and had started filming in New Zealand when he chose to walk out.
