Drew Barrymore‘s “hedonistic” upbringing was the focal point of her conversation with actress Ione Skye on this morning’s episode of The Drew Barrymore Show, with the two women looking back on their party days.

At the start of their chat, the duo remembered hanging out together at Helena’s, a popular Los Angeles club in the 1980s that stars like Sean Penn, Madonna, and Jack Nicholson would frequent.

“Oh, yeah. I used to party hard with him,” Barrymore said, referring to Nicholson, who’s nearly four decades her senior. “He was fun.”

Being around an older crowd was never unusual for the talk show host, who spent a large part of her upbringing in nightclubs.

“I was there starting … at least 8, 9, 10, 11,” she said “I had my 10th birthday at a nightclub.”

Skye, who was promoting her new memoir Say Everything, then told Barrymore, “It was a great group of adults, actually. I’m sure our mothers were friends with them so it was this weird crossover.”

While some may view the age gap as “inappropriate” nowadays, Barrymore said it felt perfectly normal at the time.

“I think what’s so interesting, when I think about the book, is that there were relationships that we had with all of these people,” she said. “Some were our age, most weren’t. And yet they were our peers, they were the people that felt right to us.”

“It’s like you could look at that and think, ‘Oh, that seems crazy and inappropriate or wild,'” Barrymore continued. “But it didn’t feel like it at the time. There was nobody talking about age, number, appropriateness. It was a hedonistic, wild, Hollywood world.”

Skye added that it was a “different time,” to which Barrymore replied, “I mean, nothing would have flown today that was happening when we were kids.”
