Justin Timberlake has revealed how fathering his 18-month-old son, Silas, who he shares with wife Jessica Biel has changed him.
"It changes everything," the singer, 35, told Today show. "You literally just wake up and look in the mirror and go, 'I have no idea what I'm doing.'"
Timberlake also admitted Silas was one of the main reasons he wrote his most recent tune, "Can't Stop the Feeling!," which was released as the lead single from the Trolls movie soundtrack.
"I don't know that [the song] 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 quipped.
Timberlake also gushed about his wife, Biel, 34, "It's crazy, [I have] this new appreciation for both of them [Silas and Jessica]. It's humiliating and it's humbling at the same time."
