Calum Best branded Janice Dickinson "crazy" after she tried to seduce him on 'Come Dine With Me'.
The 29-year-old star was left astonished by the 55-year-old supermodel's behaviour on the programme, which saw her expose her underwear to him, try to leap into his lap and threatened to quit the show unless she was given his telephone number.
Calum - who has previously been linked to a string of famous women including Sarah Harding and Lindsay Lohan - said: "She is crazy and her behaviour was definitely a bit unnerving."
After Janice pulled up her dress to show her underwear to Calum, he told her: "Go outside and have some time out."
Earlier, the American star is seen pledging: "I think it's love at first sight! He is hot to trot. Before the end of the day Calum is going to be mine.
"I could knock him over the head like a cavewoman and drag him back to the cave."
However, a show insider joked: "Janice could be the first woman Calum has knocked back."
Janice - who reportedly swigged wine throughout the show - also clashed with fellow guest Sam Fox over the British beauty's decision to embark on a career in topless modelling aged 16.
A programme spokesperson played down Janice's behaviour, saying: "It's true Janice was a bit raucous, but that's in keeping with the show's format which is very tongue in cheek."
The 'Come Dine With Me' celebrity special - also starring Jeff Brazier - airs tomorrow night.
