It has been confirmed that Jessica Biel has finally given birth to her first child with her partner Justin Timberlake. The couple has named the child, Silas Randall Timberlake, a baby boy, says People Magazine.

The couple's representatives speaking to different media outlets said that the mom and baby are doing well and dad is "ecstatic."

Also, according to the magazine, the baby was named Silas, since it was the middle name of Timberlake'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.

Timberlake, recently posted a picture of Biel being pregnant, on Instagram, on his birthday. He posted, saying, "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT," as he captioned a photo of himself kissing Biel's bare baby belly.

Reportedly, the couple was taking guesses at the gender of the baby before the delivery.

Weeks before she gave birth, Biel, 33, celebrated her own birthday"” and Timberlake once again took to Instagram to shower his wife with love. And for her birthday, he posted saying "Happy Bday to the sweetest, most GORGEOUS, goofiest, most BAD-A** chick I know. You make me smile 'til it hurts. I love you like crazy."
