The 'Turn Back Time' hitmaker was forced to cancel dates on her 'Dressed to Kill' concert last September after being diagnosed with a potentially fatal mystery virus, but she has now revealed she's made a full recovery. <br /> <br />She said: "I'm feeling great. <br />"I'm not dying!" <br /> <br />The musician sparked worries when she was spotted wearing a cardiac monitor back in October, and a source close to the star has admitted the illness was frightening as it affected her heart. <br /> <br />The source explained: "She was really flattened by the infection -- it affected her kidney function and threatened her heart. <br /> <br />"For the first time in her life, she learned how to slow down and methodically build up strength."
