Long before Simon Cowell impregnated his close friend Andrew Silverman's estranged wife, Lauren Silverman, the wealthy group of pals steered clear of the chilly winters in London and New York City and vacationed together in St. Barths in January 2012. The future parents -- photographed aboard a yacht with real estate mogul Andrew -- began seeing each other later that year.
"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 reveals in the August 12 issue of Us Weekly. "As their marriage deteriorated, she and Simon became close."
An insider adds that Manhattan socialite Lauren, 36, is "around 10 weeks along" and plans to leave Andrew to be with the acerbic X Factor judge. Though Cowell's reps were unavailable for comment, the 53-year-old Brit has said on more than one occasion that he's not cut out for fatherhood.
"God, no. I couldn't have children," Cowell once crowed. "With kids, you've got a routine you can't escape from."
Cowell made no mention of his future child during a July 30 appearance on E!'s Chelsea Lately. Instead, the former American Idol judge promoted One Direction's upcoming movie, One Direction: This Is Us, and talked about his love of alcohol, cigarettes and vitamins.
