Collin Gosselin has fellow reality star Alexia Umansky in his corner ahead of him releasing his bombshell memoir about his “dark” childhood with parents Kate and Jon Gosselin.

Collin posted pics with Umansky on Instagram Friday of the two having dinner together in Los Angeles.

“Went for the pasta 🍝 stayed for the good laughs and conversation. So good catching up with friends over dinner in LA!!” he wrote.

Umansky, the 30-year-old daughter of “Real Housewives of Beverly Hills” star Kyle Richards and real estate broker Mauricio Umansky, commented on the post, “Now you just need to move to LA! 👯.”

The “Buying Beverly Hills” star posted her own Instagram Story with Collin Friday, and shared her support for his upcoming memoir, “In the Shadow of Eight: Surviving the Reality of My Childhood,” which drops on Oct. 13.

“So proud of @collingosselin1 and everything he’s standing up for,” she wrote, adding a heart emoji. “Proud to call him my friend.”

She then posted a pic of the cover of 22-year-old Collin’s book, writing, “So many of you watched @collingosselin1 grow up… So, many of you will want to hear his story. His book is available for pre-order.”

The Gosselin family rose to fame on the TLC series “Jon & Kate Plus 8,” which aired from 2007 to 2017. The show followed Jon and Kate and their sextuplets — Collin, Aaden, Joel, Alexis, Hannah and Leah — as well as their twins, Cara and Madelyn.

Jon, 49, and Kate, 51, split in 2009 after 10 years of marriage. In 2018, Jon received sole custody of Collin.

Throughout the years, Collin has accused Kate of “child abuse and child exploitation,” which she’s denied. Her lawyer told the US Sun back in September 2024 that he didn’t believe Kate had done anything to “intentionally harm” Collin, and that she “did what she did to protect herself and her family” from her son’s “troubled behavior.”

According to the description of Collin’s book shared by the publisher, his memoir promises to reveal the “never-before-told story of how [Collin] escaped and found his way back from the dark.”

His memoir will recount him “being held down, the basement cell where he was hidden for years and the cocktail of powerful antipsychotics forced on an 11-year-old boy.”

Collin has continued to publicly take shots at his mom ahead of the release of his book, and last month, Kate called him “mentally ill.”

The mother of eight responded to a TikTok user who commented on her recent post that she empathized with being “constantly disparaged and lied about” by an “adult child with a skewed version of their childhood.”

Kate replied, “Thank you! YOU understand. Sadly, only parents who have a mentally ill child understand!”
