Simon Cowell allegedly flirted with British reality TV star Amy Childs.

'The X Factor' boss apparently invited former 'The Only Way Is Essex' cast member to his Los Angeles home following a flirty exchange at a showbiz party.

Amy, 22, revealed: ''Simon flirted with me. He thanked me for going to his house on one of those star-spotting buses while I was in LA.

''He then told me that I should knock on his door whenever I was over there. It happened at a charity event in London.

''My manager knows him so we started chatting. He said I should go and see him In America. That's Simon Cowell for you.''

Amy also told this week's Now magazine that Radio 1 DJ Fearne Cotton, 30, is the rudest celebrity she has met.

She said: ''She looked me up and down the first time we came across each other. But she was lovely the second time so maybe she was having a bad day.''

She additionally confessed she is addicted to erotic book 'Fifty Shades of Grey'.

Amy admitted: ''I'm interested because the guy's so powerful and the girl's only 22, the same age as me.

''I know the book is a lot about sexual positions but at times I just skip the sex scenes.

''Hand on my heart, I'm not into bondage and all that stuff.''
