She captioned the post: “I love a theme. Wear Pink she said! Celebrating our sweet baby girl coming oh so soon! Adore you @samanthamstone and can’t wait to meet baby Stone. She’s a lucky little girl to have a mama like you. Love, Auntie Kelly.”
Meghan was recently pictured with Ms McKee Zajfen, who’s been a close pal for a while, when they both attended a children’s hospital gala back in October.
At the time, she thanked the duchess for turning up in honour of the hospital, which has cared for Kelly’s daughter Lily, who has had a heart condition since the age of two.
She wrote on Instagram: “I was also beyond grateful to share in this beautiful evening with one of my closest friends.
“Meg, your commitment to supporting Children’s Hospital Los Angeles and community is truly inspiring. I’m so grateful to have you by my side.”
The mum-to-be, Ms Stone, looked sensational in a bright pink silk dress.
According to her LinkedIn, Ms Stone is currently the Chief Membership Officer at the exclusive Soho House club in Los Angeles, while she is also a Trustee at Children’s Hospital Los Angeles (CHLA).
