77-year-old Richie sought medical attention after his concert on Saturday night. He is now being treated in intensive care, TMZ reports.
His condition is unclear, as is why he sought treatment.
A similar incident occurred in June, when Lionel Richie interrupted a concert after feeling "dizzy" and "weird", after which he was taken by ambulance to a hospital.
Richie is behind hit songs like "Hello" and "All Night Long".
