But in the bedroom is where British model Alicia Douvall is focusing in a new interview, telling Great Britain's The Sun that she once got it on with the reality show star 11 times... in one night!
"We started having sex and went on through the night," Douvall said of a an evening not longer after she met Simon in 2001 at a bar. "We slept a little bit in between but only for a few minutes."
And how as Cowell? Critical, Douvall claims.
"Every time we had sex he would analyze my performance just like a judge on the TV and say how there could be an improvement next time."
The model says she's speaking out now because she's NOT included in "Sweet Revenge: The Intimate Life of Simon Cowell," a biography about the judge penned by Tim Bower.
As someone with first hand knowledge, purportedly, Douvall does not back up Sharon Osbourne's assertions regarding Cowell's manhood.
