Britain’s Got Talent judge Piers Morgan has threatened to write a tell all book about Simon Cowell, if his boss doesn’t ask him to be best man at his wedding.

Simon Cowell has previously admitted to being engaged to makeup artist Mezhgan Hussainy, though he has not yet confirmed their wedding date.

Piers Morgan and So You Think You Can Dance judge Nigel Lythgoe are both competing for the role of Best Man but Morgan told Now magazine:

“If Simon doesn’t let me be best man, then I’ll write a book containing all the secrets I know about him.

“Trust me, I’m getting this gig.”

Morgan also revealed that he was recently chatted up by an attractive woman who mistook him for Simon Cowell.

“An attractive brunette came up to me in an LA bar last week and purred sweet nothings in my ear about how wonderful I was.

“She rather spoilt it by saying at the end, ‘Lovely to meet you, Simon.’”
