Kids say the darndest things, don't they? Keith Urban's 5-year-old daughter, Sunday Rose, is no exception -- she has a new fad every week, and sometimes, it's a hilarious new word.

"Every week there's something new going on. There's a new move," Urban shares of his oldest daughter. Sunday's tastes change weekly, but right now, she's referring to everything as 'weird.'

"There's a new word in their vocabulary," the singer says. "Right now for Sunday, everything's 'that's weird.'"

He adds, "Everything's weird for a 5-year-old ... sometimes she's right!" Of course, Urban's got more than one funny daughter at home. His 3-year-old, Faith Margaret, probably keeps him laughing as much as her older sister.

In addition to being a loving father, the 'Cop Car' singer is keeping himself busy as a country music superstar. He's got tour dates coming up, and he's currently on top of promoting his new single. The music video for 'Cop Car' dropped promptly after the 'American Idol' judge performed the song on the 2014 Grammys with Gary Clark, Jr.

Full tour dates for Urban's Light the Fuse Tour are on his website.
