According to the News of the World, the incident occurred when Clancy returned to London for work half-way through their holiday on the French Riviera.
Jo Elliott, who met the footballer at the club, said: "It was obvious Crouch was drunk. Someone was taking a photo so I put my arm around him but Crouch took the opportunity to touch me. He had his hand all over my arm and leg.
"My dress was quite short and he was running his hand up and down my thigh and also my back. I was appalled and should have slapped him there and then.
"He was coming onto me. He asked me what I did and when I said I was a nurse his eyes lit up and he drooled, 'Oh yes, a nurse? I bet you look lovely in a nurse's uniform'. He was being a blatant sex pest.
"I asked, 'Where's Abbey?' and he replied, 'Oh I don't know. She's not come out'. Then he pulled a horrible face. At that point I got up and moved away."
A witness at the club added: "Peter Crouch was a total disgrace. About 1am I saw him kissing a woman and thought, 'What a dirty cheat! I'm going to take some photos'. How dare he. He was out on his own and extremely drunk, absolutely smashed.
"Who the hell is this guy to play away behind Abbey's back? She deserves to know what he's really like, that he was behaving like a monster even before he went with that prostitute.
"She deserves better. I saw him kiss and cuddle at least two women. But he was so drunk I'd be surprised if he can remember. That might be his best defence to Abbey."
