Simon Cowell: Blindsided By Lauren Silverman Pregnancy Bombshell?

So, Lauren Silverman and Simon Cowell are having a baby apparently.

Who saw that coming? Not The X Factor judge, a new report claims.

The 53-year-old was completely blindsided by the news that his good friend’s wife was pregnant with his baby, according to the New York Daily News.

“The pregnancy took him by surprise. He assumed she was using birth control,” a source said. “Simon thought it was a casual relationship. Friends with benefits."

"The pregnancy was not planned. He is feeling tricked. No question Simon will want to be part of the baby’s life, but I’m not so sure he wants to be part of Lauren’s.”

Lauren Silverman, 36, who was seen with Cowell and her husband, Andrew Silverman, in the Caribbean last year, is nearly three months pregnant.

She is also still married, and in the midst of a nasty divorce.

Apparently incensed over her affair with Cowell, Silverman’s real estate mogul husband filed for divorce July 15. The tryst may factor into their divorce fight.

The legal papers he filed name Simon Cowell as a co-respondent. Andrew Silverman will have to prove he is not the father to avoid paying child support.

Cowell, meanwhile, only found out about the pregnancy July 10.

“She told him around that time,” a source said. “He didn’t have a clue and it has comes as a total surprise. Simon has repeatedly said he doesn’t want kids.”

The revelation sent Cowell into crisis mode. He immediately reached out to PR guru Max Clifford to “plan a strategy to deal with it ... he feels let down by Lauren."

“They were friends first and foremost. This could be a ‘spite my husband’ sort of thing. Simon is convinced it was her friends who leaked the story.”

Cowell’s friendship with the Silvermans was no secret, and by last year, their marriage was on the rocks. Still, the pregnancy bombshell was a shock to everyone.

One of Cowell’s pals described her as a gold digger:

“She has a thing for rich, powerful men. She knows having Simon’s baby will mean he will always be in her life and he is a very wealthy and generous man.”
