The holiday weekend marked another proud-parent moment for Heather Dubrow.

On Friday, May 27, The Real Housewives of Orange County mom shared a glimpse into her daughter Kat Dubrow’s high school graduation day. Heather posted an Instagram video showing herself in the kitchen as she decorated Kat’s mortarboard with gemstones.

“This is what mothers do when their daughters say they need their [graduation] cap bedazzled at 6 a.m.,” Heather said with a laugh. “Graduation day!”

The OC ’Wife then lifted the cap to reveal her progress. She had added the letter “Y” to personalize the cap, a tribute to Kat’s selection of Yale University for college.

A few days after the graduation, Heather shared a collection of photos and videos from the ceremony. One image showed Kat holding her cap and gown, while another captured the 18-year-old walking across the stage to receive her diploma. The collection also included a photo of Kat and her classmates tossing their caps into the air and a snapshot of the Dubrow family posing next to a “2025” marquee. The family photo slide featured Heather’s husband, Dr. Terry Dubrow, their oldest children, twins Nick and Max Dubrow, and their youngest child, son Ace Dubrow.

Heather also shared photos from Kat’s graduation party at the ultra-chic Hotel Bel-Air. The event featured gorgeous tablescapes with peach and pink floral centerpieces, sage green tablecloths, and customized pencils that served as guest placecards. 

“Wow! What an incredible weekend celebrating Katarina ! So emotional, special and fun !” Heather captioned the Instagram post. “Congratulations my baby on graduating High School! We all love you so much and are so proud of how hard you’ve worked ! This is only the beginning.”

The party’s color scheme carried over into Kat’s graduation cake — a beautiful two-tiered design with light green frosting, a cap and diploma topper, and a metallic film reel, which was a reference to Kat’s intended college major.

Heather Dubrow sets the record straight on Kat Dubrow’s Yale acceptance

The RHOBH daughter announced her college selection back in April, confirming she was attending her dad’s Ivy League alma mater. Kat has decided to major in film studies, which her mom teased during a 2024 interview with BravoTV.com.

Heather spoke about Kat’s new chapter in a recent chat with Us Weekly, and addressed the online claims that she and Terry secured their daughter’s college acceptance by “donating” to Yale University.

“Oh God, listen — that ship sailed a long time ago,” Heather said, adding that Kat got into school on her own merit. “Even if I wanted to pay, that’s not a thing.

She continued: “I’ll tell you a quick story. When the twins got into kindergarten, that process of private school kindergarten was so ridiculous to me and upsetting and it gave me so much anxiety [that I said], ‘I’m never doing this again.’ So I told all the kids when they got to high school, ‘If you want choices, study, and here’s your guidance counselor and do your best. I’ll be your cheerleader, but I’m not fighting with you. This is your life. It’s up to you.’ And that’s exactly what we’ve done.”
