We knew all the intense bickering between Simon and Paula on American Idol was due to some sexual tension! Former Idol and current X Factor judge Simon Cowell confessed to Barbara Walters that he’s always known Paula wanted to sex him up. On Barbara’s 10 Most Fascinating People special, Simon explains how he was "a million percent” sure Paula wanted a relationship with him during their tenure on Idol.

So why didn’t the British playboy, currently engaged to makeup artist Mezhgan Hussainy, ever hook up with Paula? Simon explains that he was terrified of the morning after any potential tryst: "I considered it, but then I thought, 'I don't think the after would be as good as the before.' I'd let her stay for a few hours, but then it would have to be goodnight."
