Justin Timberlake shared the first photo of his new baby boy Silas Randall Timberlake on Instagram over the weekend.

Jessica Biel Poses With Baby Silas

Timberlake posted a sweet photo of his first child with wife Jessica Biel on Sunday in support of the Memphis Grizzlies, who played against the Portland Trail Blazers later that night in Game 1 of the first-round series.

In the photo, Biel cradles baby Silas in her arms. At less than two weeks old, Silas is already a fan, sporting a blue Grizzlies jersey that matches his adorable blue eyes. “The Timberlakes are ready!!! GO GRIZZ!” Timberlake captioned the photo.

Timberlake, 34, and Biel, 33, surprised fans with the photo. The private couple waited until January to confirm they were expecting – an announcement Timberlake also made via Instagram – and many believed that they wouldn’t show any photos of Silas at all.
