Last night Justin Timberlake appeared on The Tonight Show With Jimmy Fallon and brought along a few adorable photos of his 5 month-old baby son, Silas, to show the world.

Justin, like most new parents, loves fatherhood: “It is the most insanely amazing, most beautiful, unbelievable thing to ever happen to you”.

Check out the video and photos below.
