Gina Kirschenheiter and Her Ex-Husband, Matt, Reunite to Support Their Daughter, Sienna

Gina Kirschenheiter reminded fans that divorce doesn't have to mark the end of a family unit.

On Tuesday, April 15, The Real Housewives of Orange County mom took to Instagram to celebrate a big milestone for Sienna Kirschenheiter, her 11-year-old daughter she shares with ex-husband Matt Kirschenheiter. Gina reposted a photo of her and Matt saying goodbye to Sienna as she prepared to leave for sleepaway camp. The snap also featured Matt’s current wife, Britt Kirschenheiter, whom he married in 2024.

“We love You Sienna,” read the post, originally shared by Britt. “Have the best time at Science Camp.” 

Gina Kirschenheiter on the importance of healthy co-parenting relationships

Gina and Matt tied the knot in May 2010 and called it quits about eight years later. The former couple, who also share two sons, Nicholas and Luca, have since developed a loving and supportive co-parenting relationship, which includes Gina’s longtime boyfriend, Travis Mullen.

Gona spoke about the blended-family dynamics during a 2024 appearance on the Got It from My Momma podcast, saying divorces shouldn’t mark “the death of a relationship,” especially when children are involved.

“[Divorces] are an opportunity to rebirth a new relationship,” she said. “It all crashed and burned, right? But now you have an opportunity, you have this responsibility to these children that you chose to bring into this world… Show them, ‘Look, we weren’t great at [being married],’ but we love you enough… We’re still great partners. We just weren’t supposed to be romantic partners.’ There’s still pride in that. There’s nothing wrong with that. I think the crux of it all is you have to truly love your children more than you hate your ex.”

Gina Kirschenheiter reveals Matt Kirschenheiter had a heart attack

Gina shared the family update about month after Matt suffered a heart attack. The New Jersey-born mom confirmed the scary news in a March 17 Instagram post, which showed her blended family visiting Matt in the hospital. 

“The kids were very shaken up but thankfully we can be smiling bc he will be OK!” Gina wrote. “The kids and Travis and I are so happy to have their dad back. This was too close of a call. Really puts things in perspective. We will all be changing our lifestyle and leaning into the healthy [because] being there for our kids is the only thing that matters…

“Thank you for everyone who has checked in on us,” she continued. “For anyone out there struggling to coparent, remember you are all a family and what matters most is that you all get to be there for your kids. Tomorrow is not promised, today is a gift.”

Although Gina’s family life has kept her quite busy, she’s still making waves in the SoCal real estate market. Get more details about her booming career with The Gated Group.
