Just a week after Justin Timberlake and Jessica Biel became parents for the first time, the A-list duo have introduced baby boy Silas Randall Timberlake to the world ... by way of Instagram.

Timberlake posted a sweet photo of the newborn. The pic features Mama Biel cradling little Silas, who's clearly a fan of dad's favourite team, The Memphis Grizzlies, because he's wearing the (tiny) T-shirt to prove it. (Dad's also part-owner of the basketball team.)

"The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR," reads the caption.

Timberlake and Biel reportedly have plans to raise the little guy in Montana, away from the public eye. But before they do, they obviously want the world to see just how heart-meltingly adorable their baby is. Awwwwwww.
