All together now: AWWW!!

Just eight days after welcoming son Silas Randall into the world, Justin Timberlake and Jessica Biel debuted their firstborn on Instagram.

On Sunday, the proud papa posted a pic of his glowing wife and beautiful son on the photo-sharing network, captioning it “The Timberlakes are ready!!! GO GRIZZ!” The Memphis-born singer even dressed his boy up in a Grizzlies shirt for the NBA Playoffs.

Be right back, swooning so hard right now.

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