The Duchess of Cambridge has reportedly been bonding with Victoria Beckham over decorating.
They have many of the same interests, with the royal couple welcoming their son Prince George in July, while Victoria and David are parents to four children.
"The Beckhams and William and Kate are becoming very close and regularly discuss everything from parenting to decorating. Kate and Victoria have a lot in common as they both adore art and interior design," a source told British magazine Star.
"William and David enjoy discussing sport and bonding over being dads, and Kate and Victoria talk about fashion, design and parenting."
One particular area in which the two women have shared ideas is the Beckham's bathroom. The couple recently purchased a new mansion in London and are said to be spending $71.7 million on renovation. Catherine is reportedly planning a gift for their new luxury mansion.
"Kate has been advising the Beckhams on their bathroom tiles, and her and William's main bathroom is marvellous," the insider explained. "She is sourcing antique Grecian statues for them both, too, as housewarming presents."
When the Beckhams' new house is all finished they are said to want to plan a dinner party with their royal pals.
"The four of them will cook together when William and Kate visit the new house. David loves making sushi and William's keen to learn," the source added.
