Introducing the Timberlakes! Justin Timberlake debuted the first photo of his infant son Silas Randall Timberlake on Sunday, April 19 via Instagram. 

Just one week after welcoming their first child, Timberlake, 34, posted a shot of his wife Jessica Biel cradling little Silas and wrote, "The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR."

The newborn wore a tiny Memphis Grizzlies jersey to support his dad\'s favorite team. 

The fresh-faced Biel, 33, looked radiant, holding her first born son and grinning. The couple plans to raise their son in Montana, away from Hollywood. 

"Jessica sees herself as a mom of boys, so it worked out perfectly," a source told Us Weekly earlier in the week. "Justin is so excited, he doesn\'t know what to do with himself!"
