Jessica Biel and Justin Timberlake welcomed their first child to the world on Saturday, naming their baby boy Silas Randall. 

Silas was the middle name of Justin Timberlake's grandfather Bill Bromar and Randall is the middle name of the singe himself, according to People. 

Jessica Biel posted a picture on Instagram of Kodiak Cake pancake mix, which Justin Timberlake's wife says was her favorite while she was pregnant. 

"Cooking with @kodiakcakes on set the other day!" she captioned her photo on Instagram. 

"My fmce_markeramp;@?!% favorite pancake mix. If you don't know em, get to know em."

Jessica Biel and her husband Justin Timberlake were recently spotted on a date at Jon Rollo's new Greenleaf Chopshop's Hollywood while she was pregnant, which was the last time her baby bump appeared in public before birth. 

"[they] stayed together the whole night. He was very protective of her in that way. It was really nice to have them here," a source told E! News. 

"This is definitely the last time they will be out, for sure."

The couple were recently alleged to have had a disagreement over the upcoming delivery of their child.

"After some disagreement they are finally on the same page," a source told OK! Magazine.

"Jessica doesn't want any family at the hospital, including [his mother] Lynn, until the next day- so she and Justin can bond with the baby together."

The company is also said to be planning to move to Montana.

"They plan to bring the baby there. (Jessica) wants their child to experience as much mountain life as possible," a source told Us Weekly.
