Keith Urban would encourage his daughters to go into showbiz.

The 'American Idol' judge has two children, Sunday, five, and Faith, three, with his actress wife, Nicole Kidman, and likes the idea of them following in their footsteps - but only if they are willing to work hard, and says they are already showing signs of being talented performers.

Asked if he would allow them to go into showbiz, he said: ''Absolutely, if they're willing to work for it. It's not just about having talent, bit having passion. They both sing and dance, but who knows? They may go into acting or music.

''They have an iPod in their room. There's music coming from their bedroom all the time.''

The country singer is already giving Faith guitar lessons and is impressed with her skills.

He told America's OK! magazine: ''She mimics what I'm doing strumming-wise. That's what I'm trying to teach her. I love how she gravitates toward the guitar. She'll go get her little pink guitar, and hold it - she sits with it right, and she strums with it right. I hope she keeps going.''
