Model Katie Price's husband Kieran Hayler, who underwent a lie detector test, says he felt "suicidal" after not answering the questions honestly.

Hayler was forced to undertake a lie detector test when his wife suspected him of having an affair with her married best friend Jane Pountney following a steamy sun-bed encounter she stumbled across on holiday in Cape Verde, reports contactmusic.com.

Hayler lied his way through the test, which was set up by experts from `The Jeremy Kyle Show`, but instantly regretted his claims.

"After that I couldn't lie anymore. It was killing me. I went out into the field opposite Kate's house at 7.30 a.m. and lay there for four hours,` said Hayler.

"I felt suicidal. I wasn't thinking straight so I called my therapist from the field. I went back inside the house to the cinema room and admitted everything to Kate. I've watched 'Jeremy Kyle' on ITV and seen plenty of guys confessing on the show. It made me think, 'That's the person I am.'

"Kate immediately told me she couldn't be with me anymore and wanted a divorce -- and that's when she started tweeting her anger. She was devastated and threw the nearest object at me. I had her autobiography aimed at my head as well as a large candle,` he added.
