Justin Timberlake is a changed man.
During his interview with Today co-anchor Billy Geist, which aired on Tuesday, the 35-year-old singer gets emotional when talking about how being a father to his one-year-old son, Silas, has "changed everything."
"You literally just wake up, you look in the mirror and go, 'I have no idea what I'm doing,'" he quips.
Timberlake -- who's currently promoting his Netflix concert film, Justin Timberlake and the Tennessee Kids -- says that since the birth of his boy, he's more intentional about enjoying every moment. "While it's happening, now more so than ever, while it's actually happening ...the moment and all of this imperfection is the best part," he says. "That's going to be the part you remember the most."
Silas even has an impact on how his famous father is making music. "I would have never written a song like 'Can't Stop the Feeling,'" he admits of his summer hit. "I don't know that it was directly inspired to be something that my son could listen to of mine because there's a lot of music he can't listen to of mine -- at least not yet."
Timberlake also nearly chokes up talking about his wife, Jessica Biel, and what a great mother she is to their son. "I have this new appreciation for both of them, her and him," he shares. "It's humiliating and humbling at the same time."
Further gushing over Biel, the GRAMMY winner adds, "You watch her realize she has a gear she didn't have and then you go, 'Woah.'"
Timberlake also doted on his family when talking to ET, and lovingly referred to Silas as his "everything." Check out the sweet interview:
