Kyle Richards' youngest daughter is growing up so fast! The Real Housewives of Beverly Hills mom was full of emotion as she celebrated Portia Umanksy’s recent coming-of-age milestone. Kyle took to Instagram on October 3 to share memorable highlights from Portia’s bat mitzvah, including a precious father-daughter dance.

The 13-year-old twirled to Lady Gaga’s cover of “La Vie En Rose” with her dad, Mauricio Umansky, surrounded by guests who included RHOBH’s cast members Lisa Rinna, Dorit Kemsley, Crystal Kung Minkoff, and Sutton Stracke.

“Such a special evening celebrating Portia’s Bat Mitzvah,” wrote Kyle in the caption, alongside the video.

Several RHOBH cast members chimed in on the heartwarming moment in the comments. “So sweet and special,” wrote Garcelle Beauvais, while Lisa Rinna added, “The sweetest most special moments EVER” with a heart emoji.

The epic circus-themed event, held at Kyle and Mauricio’s home, also featured a video montage commemorating adorable moments from Portia’s childhood. “On the show, Portia was one-year-old turning two, and we had her 2nd birthday on The Real Housewives of Beverly Hills,” said Kyle, in a video shared on her Instagram story.

Portia, wearing a pink ombré dress and tiara, danced the night away with sisters Farrah, Sophia, and Alexia at the “Cirque du Portia” party, which featured a candy bar, carousel, and a photo booth.

Crystal shared a selfie on Instagram enjoying the cotton candy, while Dorit shared an Instagram story of her and husband, Paul "PK" Kemsley, posed in the photo booth with RHOBH alum, Teddi Mellencamp Arroyave.

“I may or may not have had more than one cotton candy at [Portia's] epic circus-themed Bat Mitzvah!,” Crystal wrote in the caption of the post. “Thank you @kylerichards18 and @mumansky18 for including us on this very special occasion. Mazel Tov!!!"
