The 53-year-old music mogul, nasty TV judge and too-tight T-shirt wearer has apparently got Lauren Silverman, 36, the estranged wife of his friend Andrew Silverman, up the duff.

A Source (the guy who knows everyone) has told the glossy mag that Lauren is leaving Andrew for good to shack up with Simon.

“Lauren and Andrew have been unhappy in their marriage for some time, and their divorce has been in the works for a while,” a source told the magazine. “As their marriage deteriorated, she and Simon became close.”

Simon and Lauren have been pictured together on holiday in St Barts.

Simon’s most recent matches include ex-fiancee, Mezhgan Hussainy and Carmen Electra, but he says he’s been single since February.
