At last night’s premiere of Rabbit Hole at the Paris Theatre, Nicole Kidman said that she'd already sat through a performance that day. Her 2-and-a-half-year-old daughter, Sunday Rose, and her husband, Keith Urban, wanted to usher her off to her big night in style. "He was playing the piano just before we left, and Sunday Rose was dancing around the living room, so that was my pre-premiere show," the actress told us. Apparently Sunday Rose, who "sings incessantly," has a repertoire of 30 songs that includes the ABC Song, "So Long, Farewell," and "Twinkle Twinkle Traffic Light" (a modern update of the old standby). But when the pint-size songstress breaks from crooning, her inner diva emerges. "She loves makeup," admits Kidman. "She's not allowed to wear it out of the house, obviously, but she pops a little blush on and some lip gloss." Once primping is completed, it's showtime yet again. "I love having music in the house," Kidman says. "For someone that can't play an instrument, it's joy." An incessant joy at that.
