Justin Timberlake is officially in the Daddy's club.
The music superstar, and his wife, actress Jessica Biel, have welcomed their first child, son Silas Randall Timberlake, confirms People.
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.
Details are being kept under wraps, but Biel is said to be doing well, and JT is "ecstatic."
The power couple kept the pregnancy a secret before Timberlake confirmed that they were expecting their first child in January (on his 34th birthday).
Congrats to the happy couple!
