Justin Timberlake and Jessica Biel have given birth to a baby boy named Silas Randall Timberlake.

The birth of the baby was confirmed to People magazine on Saturday. The couple's representatives told the magazine that the mother and the baby are doing well, and the father is extremely happy.

The baby's name, Silas, is the middle name of Timberlake's grandfather on his mother's side, who died in 2012. The baby's middle name, Randall, comes from Timberlake, who has the same middle name.

The baby has been well known long before its birth. According to Fox News, "The child's prenatal days have already been well documented on Twitter and Instagram, starting in January with Timberlake's posting of a 34^th birthday of himself kissing Biel's baby bump."

The photograph was captioned, "This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT." Timberlake recently was honored with an award at the iHeartRadio Music Awards on March 29.

After receiving the award, he made a reference to his plans to prepare before the arrival of the baby, stating "Daddy's heading home right now to innovate by learning how to change a poopy diaper and get my swaddle on!"

These public displays of affection came after several months during which the couple kept the pregnancy under wraps.

According to the hash tags that Timberlake placed on his Instagram tags, the couple was taking guesses at the sex of the baby, having chosen to keep the information as a surprise for the delivery.
