The supermodel is househunting in Los Angeles and enlisted her new friend - who lives in the American city with husband David Beckham and their sons Brooklyn, 10, Romeo, seven, and Cruz, four - to help look for a new property.
A source told Britain's Daily Star newspaper: "Kate has asked her people to contact Victoria's management.
"She wanted to know which real estate agents Victoria used and wants to go with the same people.
"She's getting tired of flying in and out of LA and thinks that getting a permanent base in Beverly Hills would be a good idea."
Meanwhile, Victoria's husband David has spoken about how much he hates being apart from his family, saying it will "kill" him to move to Italy in January.
The soccer star - who will leave his current team Los Angeles Galaxy for a six-month loan spell with AC Milan in the new year - said: "The biggest thing for me is I go away and leave my family for six months.
"They come over and see me for a week every eight weeks. Anyone who knows me knows how I feel about my children, about my wife and my family and I hate being away from them. Being away from my family and my children kills me."
