Survivor host Jeff Probst has revealed he was close to quitting the reality show after an incident during filming.

The presenter admitted he was at a loss when contestant Susan Hawk let rip at him during 2004's Survivor: Allstars series.

Hawk confronted Probst for failing to discipline another contestant - original winner Richard Hatch - who rubbed up against her naked in a previous challenge.

"It's the one and only time that I can recall not knowing what the right move was," said Probst, 42. "Everything that went through my head in terms of a response got thrown out as inappropriate or because it might hurt her feelings. So I was just standing there thinking 'shut up Jeff, shut up Jeff'."

He added: "It took me a while to get over. I really felt very bad. I had a bad taste in my mouth about it ... and I wasn't even sure I could do the show anymore."
