Despite a report by "Radar Online," Willie Nelson isn't "deathly ill." That's according to Nelson's publicist, Elaine Shock, who insists he's "perfectly fine." Earlier this month, the tabloid-style celebrity gossip site reported that Nelson is "at death's door," and has been so ravaged by emphysema and pneumonia that he can't get enough breath to sing. The story has since been picked up by other sites. Nelson canceled a series of shows in January and February because of an undisclosed illness, but made a surprise performance during SXSW on March 14th. He also performed at the Houston Livestock Show and Rodeo on March 18th.
