Timberlake captioned the Instagram photo of his wife and son with: "The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR."

Silas was born on April 11, 2015. The proud new parents gave Timberlake's middle name, Randall, as Silas' second name.

It was in October 2014 when Biel's pregnancy was confirmed by the public when, during a shopping trip, she displayed her baby bump. However, their official confirmation from the couple only came in January 2015, also via Instagram, showing the singer-songwriter kissing his wife's tummy.

Timberlake, 34, and Biel, 32, have been private about their married life, but new dad Timberlake could not contain his excitement during his wife's pregnancy. This was most notable when the "Cry Me a River" hitmaker made a lovely speech for Biel at the iHeartRadio Music Awards in late March saying he cannot wait for their greatest creation to come out.

The actress, most popular for her role as Mary Camden in the family drama series "7th Heaven," and Timberlake, who grew up in the public eye since his "Mickey Mouse Club" days until his skyrocketing fame as part of the boyband NSYNC, began dating in January 2007. Four years later, in December 2011, the couple got engaged and finally tied the knot on October 19, 2012 at the Borgo Egnazia resort in Fasano, Italy.

Before Biel got into a relationship with Timberlake, she was dating "Captain America" Chris Evans, from 2001 to 2006. Meanwhile, Timberlake was dating actress Cameron Diaz, whom she began seeing in April 2003, until the relationship ended in December 2006.
