David thrilled by Simon's reported impending fatherhood

David Walliams has spoken out about unconfirmed claims that Simon Cowell is expecting a baby with New York socialite Lauren Silverman.

The comic – who works with Simon, 53, on Britain’s Got Talent – took to Twitter yesterday after hearing allegations that Lauren, 36, is reportedly having Simon‘s first child.

‘Oh yeah, and @SimonCowell is doing a baby with a lady,’ Tweeted David, 41.

Simon‘s alleged situation is complicated by the fact that Lauren is still technically married to his close friend Andrew Silverman, although their divorce is said to have been ‘in the works for a while’.

Dad-of-one David couldn’t help making a silly joke about the rumours.

‘For the record @SimonCowell and I tried to have a baby together for many years. But I just couldn’t get pregnant,’ Tweeted David.

A spokesperson for Simon tells Now Online: ‘This is a very sensitive issue and all media enquiries are being dealt with by his US attorney.’
