Jessica Biel and Justin Timberlake Share First Picture of Baby Silas

Altogether now: Awwwww.

Really, there’s no other possible reaction to the first photo of Justin Timberlake and Jessica Biel’s new arrival, Silas. Timberlake posted the picture Sunday night on Instagram.

The adorable baby was born one week ago. As is evident from his cute t-shirt, he is already rooting for his dad's favorite basketball team, the Memphis Grizzlies, who opened the NBA playoffs with a victory over the Portland Trailblazers.

"The Timberlakes are ready!!!" Timberlake captioned the photo on Instagram. "GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR."
