Congratulations all around! Kim Richards and her pregnant daughter, Brooke Wiederhorn, attended Nicky Hilton’s lavish baby shower at the Hotel Bel Air on Friday, May 13.

The grandma-to-be and Real Housewives of Beverly Hills star, 51, shared a sweet photo on Instagram of herself cradling Wiederhorn’s baby bump at the party.

“A mothers joy begins when new life is moving around inside... and those playful kicks that remind her she’s never alone,” she captioned the pic. “NANA waits for those moments too.”

Wiederhorn, 30, who is Hilton’s cousin, is expecting her first child, a baby boy, with husband Thayer Weiderhorn. The couple tied the knot in 2014.

Last month, Paris Hilton revealed that sister Nicky, 32, and her hubby, James Rothschild, are expecting a baby girl during an exclusive chat with Us Weekly Video.

“I’m so excited for the baby,” the hotel heiress gushed. “She’s going to be such a beautiful little girl, and I can’t wait to meet her!”

The Simple Life alum also shared a group shot of herself, Nicky, Richards and Wiederhorn on Instagram at the baby shower on Friday, which she captioned, “I’m excited to be an aunt for the first time. And my aunt @KimRichards is thrilled to be a grandma for her first time!”
