Nicole Kidman's Grammy-winning hubby Keith Urban isn't the only crooner in the household.

At the NYC premiere of her new drama Rabbit Hole Thursday, the actress -- who showed off her own vocal talents in Moulin Rouge -- told their two-year-old daughter Sunday "sings incessantly!"

Continues Kidman, "She has a repertoire of about 30 songs: 'The ABCs', 'Twinkle, Twinkle Traffic Light' -- have you heard that one? And 'So long, Farewell,' she was singing that as I left the house."

According to Kidman, her tot's talents aren't limited to just her voice. When her dad gave a quick at-home performance before they left for the premiere, "Sunday Rose was dancing around the living room," the Oscar winner, 43, told Us.

Adds Urban, 43, of his little girl's skills, "I'm your typical proud dad."

And if Sunday decides to forgo showbiz, she could have a future as a stylist.

"She loves makeup," Kidman told Us, adding that she often helps her prep for premieres. "She's not allowed to wear it out of the house, obviously, but she pops on a little blush and some lip gloss!"
