Meet Silas Randall Timberlake.

New parents Justin Timberlake and Jessica Biel introduced their newborn son via Instagram Sunday. “The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR,” the proud new papa, 34, captioned the image of his wife, 33, and son.

The A-list couple welcomed their first child earlier this month.

Silas was the middle name of Timberlake’s maternal grandfather, while Randall is Timberlake’s father’s name and also the singer’s middle name.

The couple has remained mum on all other birth news – including their son’s actual birth date and weight/length – at this time.
