It's a boy for Justin Timberlake & Jessica Biel.

Justin Timberlake and his wife, actress Jessica Biel, have welcomed their first child, son Silas Randall Timberlake, their reps confirm to People exclusively.  Reps say mom and baby are doing well and dad is “ecstatic.” Further details are being kept private at this time.
Silas 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.

After months of keeping Biel’s pregnancy under wraps, Timberlake finally confirmed (on his 34th birthday in January) that the couple were expecting a baby together.
“Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT,” he captioned a photo of himself kissing Biel’s bare baby belly.

According to Timberlake’s hashtags, the couple were making guesses as to the sex, after opting to keep it a delivery surprise.
