Nicole Kidman is on the hunt for a new home — and her number one priority is to find a property near best pal Naomi Watts.

After spending time with her kids at Watts’ L.A. pad, the Hollywood star got her people to do a bit of house hunting on her behalf.

“Nicole had her people call Naomi’s next-door neighbors to ask if they would be interested in selling their house — even though it wasn’t on the market,” a source says of Kidman — who’s married to country music star Keith Urban, and often stays at Watts’ house.

Naomi’s neighbors refused the offer, but Nicole has continued in her quest to find her perfect house, and is looking at properties in the $8 million range.

“Her favorite property so far is a Nantucket-style home. Although the home is not on Naomi’s block, it is within walking distance,” the source adds to Us Weekly magazine.
