Gladys Knight canceled a concert Saturday night in Florida after she fell ill backstage.

TMZ was the first to report the R&B legend came down with the flu before the show and was treated in Florida.

She was released overnight.

Knight, 80, shared an update with fans on social media.

Knight reassured fans that she was “already feeling much better” as she revealed she had “that flu that is going around.

“I’ll see everyone real soon and appreciate the good wishes.”

“Tonight’s performance by Gladys Knight was cancelled due to illness,” a Florida Theater statement said. “Ms Knight and another member of her staff were taken ill backstage, very suddenly, and at the last minute, which necessitated the sudden cancellation of the show.

“We hope to reschedule the show, but it’s too early to know about that… we should know more early next week.“
