Richards' husband, Mauricio Umansky, 51, also shared a sweet birthday post for Portia, along with photos taken from her younger years to the present.

"Wishing my favorite person; my little love a very very Happy Birthday," he wrote in the caption. "I love you ❤️😘💕"

Portia is Richards and Umansky's youngest child. The couple also shares daughters Alexia, 25, and Sophia, 22. The real estate mogul also helped raise the reality star's eldest daughter, Farrah Aldjufrie, 33, whom she shares with ex Guraish Aldjufrie.

In November, the pair opened up about their relationship with their four kids during an exclusive joint interview with Bravo Insider.

"My husband and I are very fortunate. And with our family we are very fortunate," Richards shared. "We are a family that loves to be together, and we do everything together with our daughters. And we genuinely love hanging out together."

As to their daughters' possible life partners, the "Halloween Kills" star hopes that they "find someone that they can love to spend time with and have a big family, 'cause I know they want that as well."

She added, "At the end of the day, I just want them to be happy. Whatever that is, I want my daughters to be happy and with someone that will support them and cherish them and respect them. Because otherwise, they’re gonna have to deal with me, and they do not want to do that [laughs]."

As for Mauricio, he hopes for his daughters' partners to have a good dynamic with the whole family.

"I just pray that we all get along with the boyfriends or the fiancés or the husbands, whatever, because we are a super tight family, and we love to all be together," he noted.

Farrah got engaged to boyfriend Alex Manos in November, and the whole fam seemed to adore her future husband.

Richards shared pictures from their engagement celebration, such as an image of the couple and their cake. She captioned the share with:

"My baby @farrahbritt is getting married! We love Alex so much and couldn’t be happier!! Congratulations Farrah & Alex 🙏❤️ 💍👰🏻‍♀️"
