Britain's Duchess of Cambridge is thought to have turned to Victoria Beckham for tips on raising her son.
The 32-year-old royal and her husband Price William recently celebrated the first birthday of their son Prince George with a fun party.
As the tot gets older, Catherine - known as Kate Middleton prior to her nuptials - is said to be relying on former Spice Girl Beckham for parenting advice as she is a mother to three sons and a daughter herself.
The Duke of Cambridge is close pals with the fashion designer's soccer star husband David Beckham, which means the wives have also reportedly formed a friendship.
"Victoria's three boys are so well-behaved and comfortable in the spotlight that it's clear she's done an amazing job raising them," a source told British magazine Look.
"No doubt Kate's asking for tips on discipline and potty training already!"
The former pop star is also said to be urging Kate to expand her family so George has a sibling or two while growing up.
In return, Beckham is reportedly pleased to have the company since moving back to London from LA, where she and her family lived during her husband's time playing for soccer team LA Galaxy.
"Leaving LA meant losing celeb pals such as Eva Longoria, but it seems Victoria's hit it off with Kate, and it wouldn't surprise me if they email and text all the time," the insider added.
"I think Kate must really respect how Posh is a self-made woman, and Victoria can help her deal with living in the public eye.
"The couples are growing ever closer, which could lead to a joint outing.
"Kate and Victoria get along so well, they could well be planning double dates with the hubbies," the source said.
