Simon Cowell is under pressure to respond amid reports he has fathered a child. The music mogul was lying low on Wednesday (31Jul13) following the publication of allegations on UsMagazine.com suggesting New York socialite Lauren Silverman is expecting his baby. Editors at the website allege "multiple sources" have confirmed Silverman is around 10 weeks pregnant and that Cowell, who is a friend of Silverman's estranged husband, is the father. A member of Cowell's publicity team in London tells WENN it is a "very sensitive issue" but referred all inquiries to his team in the U.S., who had not responded to a request for comment as WENN went to press. In March (13), Cowell and Silverman were photographed together in the back of a limousine after a night out at a theatre, while the pair has also been photographed on vacation together.
