Baby Silas Timberlake made his Internet debut Sunday when proud daddy Justin Timberlake posted a picture of his wife, Jessica Biel, cradling their new son.

Silas is sporting a Memphis Grizzlies shirt in support of the team during last night's NBA playoff game.

 The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR

"The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR," Timberlake captioned. 

Perhaps little Silas is a good luck charm for the team - the Grizzlies ended up beating the Trail Blazers last night 100-86.
