Diana—who is also mom to son Innis, 24, and daughter Eneya, 20, from her previous marriage to Roger Jenkins—made her debut on The Real Housewives of Beverly Hills last year for season 12.

During her time on the show, the reality star shared her experience with pregnancy loss. At the beginning of the year, Diana confirmed that she was pregnant again and that she would be leaving the show.

"As so many of you know, Asher and I are expecting our second child later this year," she wrote on Instagram Jan. 9. "You also know that due to many factors, this pregnancy is considered high risk and I am on doctor-advised bed rest. To that end, I am not able to devote myself fully to filming the next season of Real Housewives of Beverly Hills. I would like to thank Bravo and Evolution for allowing me to focus on my pregnancy, and for their support and understanding. I promise to continue sharing my fertility journey with you."

Over the next few months, Diana continued to give fans glimpses into her pregnancy.

"I wish happiness was contagious I would spread it around with all my heart with love and kindness," she wrote in a July 14 Instagram post while sharing a photo of her baby bump. "9 month waiting game unicorns babies puppies and good vibes only."
