Simon Cowell accused of adultery in Andrew and Lauren Silverman’s divorce papers

Simon Cowell was named in divorce papers filed by his married lover Lauren Silverman’s husband Andrew, as his brother blasted the music mogul for his “betrayal”.

Alexander Silverman insisted that news of Lauren’s pregnancy constituted a breach of trust by Simon Cowell, as he had been close friends with both Lauren and millionaire casino owner Andrew.

He told the New York Post: “It is an unbelievable story of betrayal. It is a sad story and a tragic story.”

Alexander Silverman’s comments came as it was reported that Andrew had made the unusual choice to name Simon Cowell as a co-respondent in the divorce papers he filed in the Manhattan Supreme Court two weeks ago, citing adultery as the reason for ending the marriage.

The decision, widely regarded as a means to embarrass both Simon Cowell and Lauren Silverman, means that Cowell is likely to be called to the witness stand to reveal not only details of the alleged affair with Lauren but also details of his personal finances, estimated to be in the region of $350 million.

Noted divorce attorney Martha Cohen Stine said of Andrew Silverman’s decision: “It’s really a signal to the spouse who cheated that the wronged spouse is very angry and that it’s going to be a very nasty, scorched-earth, high-profile litigation.”

No evidence has been revealed so far to suggest that Simon Cowell and Lauren Silverman’s affair started before the marriage began to fall apart.

Simon Cowell, 53, maintained a stony silence on the subject as he was pictured for the first time since the pregnancy revelations while leaving a television studios in Los Angeles after filming The X Factor on Wednesday night.

Wearing a grey top and jeans, Simon Cowell, who is said to be “freaked out” by the news he is to become a father for the first time, remained silent as he was quizzed about the baby news, but did not deny the reports.

It is understood that Simon Cowell has hired tough Los Angeles-based lawyer Marty Singer to help him handle the crisis, described by friends as being of gargantuan proportions.

While Simon Cowell is said to accept that the baby, due next February, is his, the news of 36-year-old Lauren Silverman’s pregnancy came as a huge shock to both Simon and his closest female friends including Sinitta and ex fiancée Mezhgan Hussainy – otherwise known as his “harem”.
