Little Sunday Rose can't walk or crawl yet, but when she's ready, she'll have a huge mansion to play house in. Nicole Kidman and Keith Urban just spent $4.7 million dollar on a gated, five-bedroom, five-bathroom contemporary-style home in Beverly Hills.

"It’s very modern with treetop and canyon views, and it has complete privacy,” an insider tells Us Weekly. “It is a very light home with floor-to-ceiling windows and lots of glass.”

Adds the source, “They've been looking for more than a year and finally decided this house was the one.”

Their new neighbor includes Jessica Simpson. BH has gone country y'all!
