According to several UK based reports, the pair have become close friends in recent months and Meghan has been "leaning on Victoria as her due date draws closer."
"The girls have formed a close friendship," a royal insider told New! magazine, adding the two women have boded over their "love for fashion, living in Los Angeles and building a thick skin to deal with negativity and backlash."
The source continued: "Posh has been instrumental in helping support Meghan, who has a few friends in the UK or real family to lean on."
Victoria, who shares four children with husband David, has even offered her pal some friendly parenting advice.
"She's helping her prepare for motherhood by giving her as much parenting advice as possible - especially when doing it with the world watching," the insider adds.
In fact, the duo have been spending so much time together that according to Closer magazine, the style guru admit she's keen to have another baby - but ultimately, it's up to David.
"Vic is pleased to see her friends so happy, but she can't help but compare it to her own life," a source told the publication.
"While Meghan and Tana (another pregnant friend of Victoria's) seem to be on cloud nine, Vic spends a lot of time working hard on her fashion business while David is away."
