Singer Justin Timberlake says being a father has "changed everything" in his life.
Timberlake, who has 18-month-old son Silas Randall with wife Jessica Biel, has found "new appreciation" for his other half since the arrival of their son, reports eonline.com.
"It changes everything. You literally wake up and look in the mirror and go, 'I have no idea what I'm doing'," Timberlake said on the "Today" show.
"It's crazy. This new appreciation for both of them, her and him, it's humiliating and it's humbling at the same time... You watch her realise she has a gear she (thought she) didn't have and then you go, 'Woah, yeah'," he added.
