United Kingdom, June 29 -- Muni Long has embraced a "much more healthy lifestyle" since undergoing a double lung transplant.

The 37-year-old Grammy-winning singer, who was diagnosed with lupus in 2014, underwent the life-saving surgery after doctors gave her just a week to live - and she's now revealed she's "feeling good" and she's doing everything she can to stay healthy as she recovers.

She told The Hollywood Reporter: "I'm feeling good, as long as I do everything I'm supposed to do. Make sure I take my [face] mask everywhere, take hand sanitizer - it's really how we should all be - but I'll be a lot more cognisant of my surroundings, and what I'm eating, and things like that.

"It's actually a much more healthy lifestyle."
