On Sunday, Justin Timberlake greeted his fans with the first image of his week-old-son Silas Randall Timberlake (looking adorable in the arms of mommy Jessica Biel) on Instagram.

“The Timberlakes are ready!!! GO GRIZZ!” Timberlake captioned the picture.

Silas looked adorable in a Memphis Grizzlies shirt, which interestingly Timberlake is a part owner of.
