Kim Richards is a new grandma!
A source tells ET that Brooke Wiederhorn, daughter of the former Real Housewives of Beverly Hills star, gave birth to a baby boy on Wednesday.
The adorable new addition to the family is the first child for Brooke and her husband, Thayer Wiederhorn, and is Richards' first grandchild.
A week before Brooke delivered her baby, she took to Instagram to celebrate her mom's 52nd birthday, where she gushed over how wonderful the reality star is going to be as a grandmother.
"Happy birthday to the most amazing mom in the world! I know you will be an even more amazing grandma!!" Brooke, 30, captioned a sweet mother-daughter snapshot. "I love you!"

Brooke, whose father, Monty Brinson, died after a long battle with cancer back in January, announced she were expecting back in March.
"Happy Easter," she wrote alongside a photo of tiny baby clothes inside of an Easter basket. "Can't wait to meet our baby BOY!"

Brooke snapped a number of photos of her growing baby bump over the course of her pregnancy, which she shared to Instagram to document her journey.

Two weeks ago, she bared her belly in this heartwarming black-and-white photo, which she captioned, "Mommy & Daddy Can't Wait To Meet You!"

Back in August, Richards took to Instagram to share a photo of her kissing her daughter's stomach, and marveled in the caption, "It's amazing how much we love him already."

Congrats to the happy couple and the brand new grandma!
