Justin Timberlake and Jessica Biel have had their first child together and called him Silas Randall.

A spokesperson for the couple confirmed actress Jessica had given birth on Saturday.

Actor and singer Justin, 34, is said to be 'ecstatic', and both mother and baby are doing well.

Justin's mum, Lynn Harless took to her Facebook page to confirm the news and congratulate her son and daughter in law. She wrote: "My amazing son and his beautiful wife have given us the most precious gift in the world!

"Silas Randall Timberlake! Named after my father and my son! Life is beautiful and we couldn't be happier! God bless you all and thanks for all the congrats!"

The couple only confirmed the pregnancy on Timberlake's birthday in January, by posting a picture on his Instagram page.

"Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT," he wrote with a photo of himself kissing his wife's bare baby belly.
