Alongside the adorable snap, the 36-year-old entertainer wrote, "When you're the only Dad at the mid-morning play-class, if you stay any longer than 20 minutes... THIS IS YOUR FATE. #dadlife."
Too cute! And it seems like he's not too dismayed with this particular "fate," ha. Those neon play glasses actually look made for him -- you know, like they belong in his next music video, right?
Timberlake and Biel have been pretty private about parenthood, but more notably, sharing photos of their 2-year-old. Still, last week, for Father's Day, JT posted this sweet collage of photos with Biel and Silas (the little boy's face mostly obscured in the shots), writing, "These 2 angels... The greatest gift I've ever known. And, the reason I won't EVER STOP! Happy Fathers Day to all the Dads out there! Hope you are enjoying! #Howearlyistooearlyforafathersdaybeer."
No matter how much or little we get to see of Silas, it's always sweet to get a glimpse the family man side of the pop star.
