Simon Cowell is expecting his first child with his friend's wife, according to a report in the US media.

Showbiz magazine US Weekly is claiming that multiple sources informed them that The X Factor guru and New York socialite Lauren Silverman are expecting a baby together.

According to an insider quoted by US Weekly, Silverman is "around 10 weeks along."

Silverman is married to real estate mogul Andrew Silverman, however, the magazine claims that she is planning on ending her marriage to be with Cowell.

A source said: "Lauren and Andrew have been unhappy in their marriage for some time, and their divorce has been in the works for a while. As their marriage deteriorated, she and Simon became close."

Representatives for Cowell have not yet commented on the story.

He split from his long-term girlfriend Mezhgan Hussainy earlier this year and has previously been romantically linked to Sinitta, Terri Seymour and Carmen Electra.
