Alec Baldwin is opening up about one of his deepest regrets from his divorce from Kim Basinger—how it affected their daughter, Ireland Baldwin.

During an episode of the TLC reality series The Baldwins, Alec actor reflected on the lasting impact of his highly publicized 2002 divorce and custody battle, which played out in the media for years.

"I must say that because my relationship with my daughter Ireland was so negatively impacted by my divorce from her mother and having a very protracted custody battle that the media really were having a party about everything," Baldwin shared. "[It] went on for seven years, of which the financials were probably a year and a half and then everything else was custody."

Describing the ordeal as "just insanity" and "really, really tough," Baldwin admitted, "One of my most regrettable things about the whole thing was how it affected Ireland."

Baldwin and Basinger were married from 1993 until 2002, with their daughter, Ireland, caught in the middle of their bitter split. The divorce was marked by a lengthy custody battle, including a highly publicized 2007 incident in which an angry voicemail Baldwin left for then-11-year-old Ireland was leaked. The fallout led to a temporary loss of his visitation rights, and Baldwin later issued a public apology.

Despite past tensions, Baldwin shared that his relationship with Ireland has improved.

"She loves the kids. I mean, she's very sweet to them, and she's their older sister, but she's not in that pack," he noted. "This is why I think I'm so focused on [oldest daughter] Carmen, and I want to have a good relationship with Carmen, because I have a girl all over again."

Since his divorce from Basinger, Baldwin has remarried and started a new chapter with his wife, Hilaria Baldwin, whom he wed in 2012. The couple shares seven children—daughters Carmen Gabriela, María Lucía Victoria, and Ilaria Catalina Irena, and sons Rafael Thomas, Leonardo Ángel Charles, Romeo Alejandro David, and Eduardo Edu Pao Lucas.

Meanwhile, Basinger also spoke positively about where she and Baldwin stand today.

"Alec and I have a great relationship. I have great respect for where he is today and his family," she said. "We don’t spend Christmas and holidays together or see each other very much. But we talk. He’ll pick up the phone and call me, and we have a very genuinely cordial and, I think, loving relationship in a lot of ways, just because we share a daughter, and I don’t wish him anything but everything good."

Basinger has previously spoken about the challenges of their divorce, calling it "heavy-duty" during a 2022 appearance on Red Table Talk. She also acknowledged their differences in parenting styles, saying at the time, "We’re all fine and we all get along, whatever ... but he’s a challenge."

Despite past struggles, both Baldwin and Basinger appear to have found peace, focusing on their daughter and their separate lives.
