Lionel Richie was admitted to the ICU at a St. Louis-area hospital late Sunday, just a day after headlining a sold-out show at The Muny amphitheater in Forest Park, where witnesses said he appeared to struggle late in the set and asked his team for a chair so he could sit down during his closing number, "All Night Long."

Richie, 77, checked in "out of an abundance of caution" for tests, with doctors investigating possible mild dehydration, according to TMZ, which first reported the hospitalization. Sources close to the singer said he hoped to be discharged Tuesday. His representatives had not responded to requests for comment as of publication.

Second Scare of the Summer

This marks the second time this summer Richie has needed medical attention during a live performance. On June 24, he grew visibly dizzy about an hour into a show at Grand Casino Arena in St. Paul, Minnesota, sat down mid-song and was subsequently taken to a hospital. He postponed two follow-up shows, in Chicago and Columbus, Ohio, on doctors' orders.

WHEN YOU'RE FEELING DIZZY, SIT YOUR A** DOWN

Richie made that quip to the St. Paul crowd in June as he lowered himself into a chair mid-performance, a moment that went viral at the time. He later posted a fuller update on social media: "Thank you for every message, every kind word, and for all your love. I'm doing well, and I'm grateful for all of you," according to coverage from Fox News.

Richie has remained a fixture on the summer touring circuit and awards-show stage for decades, from his Commodores days through a solo career that includes Grammy wins and a Kennedy Center Honor. Fans and fellow artists flooded social media with well-wishes following news of the ICU admission, per KTLA's report.

What's Next

No word yet on whether Richie's remaining 2026 tour dates will be affected by this latest hospitalization. His team has not announced any cancellations beyond the two shows postponed in June, and reps have not said when a fuller health update might come.
