Justin Timberlake posted the first photo of baby Silas on Instagram on Sunday.
The picture features Jessica Biel cradling her newborn son and he captioned it:
"The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR."
The pair welcomed Silas Randall Timberlake into the world last weekend and the couple was reportedly ecstatic to share the news.
Even Silas grand-mom, Lynn Harles was over the moon about the newest addition to the family.
