Simon Cowell's former flame has dished the dirt on her romance with Max in the past, comparing him to a rabbit with no ''technique''.

''He was wearing Mr Men boxers and that was a major turn-off. They said Mr Perfect which he definitely wasn't. I couldn't take him seriously, he was like a jumped-up little boy.
''At the end I was like, 'What happened?' It was very rushed. He's got a lot to learn. I just wanted it to be over as quickly as possible.''
