At 91 years old, Willie Nelson continues to tour and perform across the country. But a recent health scare saw fans concerned for him as he pulled out of his performance at Outlaw Music Festival "per doctor's orders".
A statement on X read: "We regret to inform you that Willie Nelson is not feeling well and, per doctor's orders, has been advised to rest for the next four days."
"He is expected to make a quick recovery and join the Outlaw Music Festival tour next week. In the meantime, Lukas Nelson and the Family Band, along with a few guests, will perform a special set to include Willie's classics and other songs."
It was revealed that the country star was going to be okay, with his rep telling Today.com: "Willie will be fine. I live in Los Angeles and will fly next week to see the performances on the east coast. I can't wait."
But there have been times when Willie's health updates have taken a more serious turn.
Here, we take a look at his health issues over the years.
1981 - collapsed lung
Willie suffered a collapsed lung while swimming in Hawaii in 1981, which led to him being taken to the Maui Memorial Hospital. His scheduled concerts were canceled as a result.
In response to the significant lung congestion, Willie temporarily stopped smoking cigarettes, resuming when the congestion ended. At this point, he was smoking between two and three packs per day. After suffering from several bouts of pneumonia, he made the choice to quit smoking tobacco, but continued to smoke cannabis.
