Justin Timberlake totally went from heart throb singer to doting dad in what seemed like 0.2 seconds.
He's currently promoting a concert-film on Netflix called Justin Timberlake + The Tennessee Kids, so when E! caught up with him, they asked him what he likes to do with his kid, Silas.
"I have a 17-month-old, there's not a lot of chilling happening right now. But I've got to say, man, it's just fun to sit and watch him.
"We do a lot of "Row, Row, Row Your Boat. He does his abc's."
And then, Justin RAPPED the alphabet: "And I'm like, 'Next time you won't sing with me,' and he turns around and he goes, 'Me!' And it's like, 'You're a genius!' You know, he's everything and I just like hanging out with him."
Aw, so cute!
