Muni Long shared her shocking health crisis that led to a double lung transplant, revealing the struggles she faced during 'The Boy Is Mine' tour.

Grammy-winning singer-songwriter Muni Long has revealed the devastating health battle that forced her to leave Brandy and Monica’s “The Boy Is Mine” tour early last year.

Speaking in a recent interview with Robin Roberts on "Good Morning America", Long shared that what initially seemed like a health setback turned into a life-threatening situation that ultimately required a double lung transplant.

The singer, who joined Brandy and Monica on their highly anticipated “The Boy Is Mine” tour alongside Kelly Rowland, admitted that she probably should not have gone on the road in the first place.

“I should have never taken that tour. But there was so much going on in my life where I had to do it,” she said.
