Lionel and ex-wife Harvey took in Nicole (born on 21 Sept., 1981) when she was a toddler. According to People, the former TV personality's parents were friends of Lionel's who couldn't afford to take care of her financially, so the musician and his then-wife officially adopted her when she was 9 years old.
"Nicole was actually a godsend," Lionel previously told People of adopting his oldest daughter. "She was a little girl who needed a shot. She was used to people coming and going. She looked at me and I'd say, 'I'm not going anywhere.'" The singer added that he and Harvey "didn't agree on a lot of things, but we did agree on [Nicole]."
Nicole, who famously appeared in reality TV series "The Simple Life" with Paris Hilton from 2005 to 2007, has been candid about the controversies she's found herself in previously — including arrests, car accidents, and a struggle with substance abuse. In 2006, she told Vanity Fair that she "liked the fact that my parents weren't speaking" at that time "because I could play them against each other." "Their way of making me happy was to say yes to everything I wanted," she added, "but I don't think a little girl should have that much freedom."
She later turned to her parents for help with her drug addiction, a time Lionel later recalled having to "survive." "Forget about surviving 40 years in the music business. Just surviving 27 years of Nicole Richie has been a struggle-and-a-half," he said during the 2008 TV Land Awards (via CBS News). "I stand here as a survivor, I want you to know, for all the parents out there."
However, today, Lionel and Nicole are in a much better place. While on "The Drew Barrymore Show" in March 2023, Lionel said of raising Nicole, "If I lived through that. I can live through anything." He also added that his oldest, now a wife and mother of two, has since "turned out perfectly."
