Osmond said she now suspects that the fires may have contributed to her temporary loss of consciousness.
"The air quality is really bad and I have allergies really bad so maybe that was it," she said. "I am a singer. I don't know why I should have been winded. We have done it six seven times in a row no problem."
Though some reports have suggested Osmond's fainting spell had to do with her diet - one which has seen her lose 20 pounds, Osmond said that is simply not the case.
"Absolutely not!" she protested. "Honestly, I have never felt better in my life. I am in better shape than I ever have been and there has been so many things going, it is so funny how rumors start. No diet pills."
