Representatives for the couple have confirmed Silas Randall Timberlake and his mum are happy and healthy and the celebrity couple is "ecstatic" about the new arrival.

Timberlake ended month of baby rumours and confirmed he was set to become a dad on his 34th birthday at the end of January (15).

He shared a photo of himself kissing his wife's baby bump on social media and added the caption: "Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT."

And the singer gushed about impending fatherhood as he picked up the Innovator Award at the iHeartRadio Music Awards on 29 March (15), when he said, "I can’t wait to see our greatest creation yet. Daddy’s heading home right now to innovate by learning how to change a poopy diaper and get my swaddle on!”

Details of the baby's birthplace and date have not yet been released.
