Kim Richards has been called a lot of things in her lifetime but now she's being called something else... Grandma.

The former "Real Housewives of Beverly Hills" star's daughter Brooke Wiederhorn gave birth to a baby boy on Wednesday, according to multiple reports.

It's the first child for Brooke, 30, and it's the first grandchild for Kim.

Just last week, Brooke, whose father is Kim's late ex-husband, Monty Brinson, showed off her bump on Instagram while wishing her 52-year-old mom a happy birthday.

"Happy birthday to the most amazing mom in the world!," she wrote. "I know you will be an even more amazing grandma!! I love you! πŸŽ‚πŸ’•πŸŽ‚πŸ’•πŸŽ‚πŸ’•πŸŽ‚πŸ’•."

A week prior, the blond beauty shared a gorgeous black and white image of herself cradling her bump, captioning the image, "Mommy & Daddy Can't Wait To Meet You! πŸ’™πŸ‘ΆπŸ’™."

Brooke has often shared images of her mother touching her belly throughout the pregnancy, telling her last month, "Just a few weeks and you will be a Grandma."

The new mom took to Instagram back in the spring to tell her 85,000 followers that she and husband Thayer Wiederhorn were expecting a little bundle of joy.

"Happy EasterπŸ°πŸ’!," she said. "Can't wait to meet our baby BOY! πŸ’™πŸ‘ΆπŸ£."

Kim, of course, has had her fair share of ups and downs -- specifically when it comes to alcohol abuse -- but said that the idea of being a grandma helped her get healthy.

"I will be here to be a grandma," she tearfully told Entertainment Tonight in July 2015. "I will be here to watch my kids be married. I will do that because I am healthy, I am strong and I am going to be here for all of that and my kids will trust me to watch my grandchildren and be there."
