Lionel Richie is getting real about his sex life! While appearing on The View with his American Idol co-judges Katy Perry and Luke Bryan for an interview on Tuesday, the R&B icon spoke about his signature hit "All Night Long (All Night)" in honor of its 40th anniversary — and revealed its sensual lyrics no longer ring as true at 73 years old as they once did.

Asked by The View co-host Sara Haines to explain the meaning behind the song, Richie said, "Let me give you the first part that I have to really, really say to you. When I wrote 'All Night Long,' it was truly all night long."

"Now my 'all night long' is down to a fierce 15 minutes," he added as the hosts laughed. "But, don't worry, we'll talk about that later!"

Perry, 38, appeared shocked by Richie's remark and reached out to shake his hand. "Fifteen minutes, that's long, bud," she told the Commodores musician. "And don't you forget that, alright?" quipped Richie in response. "As long as it's not four times a night, seven days a week," added Perry. Richie then recalled the song's writing process. "I had everything but the hook," he explained, noting that he visited a friend named Lloyd in Jamaica for Thanksgiving and came up with the lyric during dinner.
