Hitchcock actress Jessica gave birth to a son, it has been confirmed.
And the Hollywood couple have named their baby boy Silas Randall Timberlake.
Silas was the middle name of Justin's maternal grandfather Bill Bomar, who died in 2012, while Randall is the musician's own middle name, as well as his father's first.
A rep told People that Jessica, 33, and newborn Silas are doing well while Justin is "ecstatic".
In January - on his 34th birthday - Justin confirmed he and wife Jessica were expecting a child in a message on Instagram.
Alongside a picture of himself kissing her pregnant belly, he wrote: "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets."
Last month, Jessica celebrated her own birthday and 'My Love' singer Justin once again took to Instagram to write a gushing message to his wife.
He wrote: "Happy Bday to the sweetest, most GORGEOUS, goofiest, most BAD-ASS chick I know. You make me smile 'til it hurts. I love you like crazy."
At the recent iHeartRadio Music Awards on March 29, Justin received the Innovator Award and paid tribute to Jessica in his acceptance speech.
He said: "I want to thank my best friend, my favourite collaborator, my wife Jessica at home. Honey I can't wait to see our greatest creation yet.
"Don't worry, daddy's heading home right now to innovate by learning how to change a poopy diaper and get my swaddle on."
Justin and Jessica married in Italy in October 2012 after dating on and off for five years.
Congratulation to J and J - we can't wait to see photos of the little tot!
