The R & B star took her nil but Love shows to Australia this month, but the tour has been marred by complaints from critics and fans Down Under who claim she has been harassed to complete her sets.
Houston supposedly coughed her way through a show in Brisbane, taking usual breaks to catch her breath, while fans are reported to have walked out of her concert in Sydney when the singer's voice began to crack.
Her voice recently shrugged off rumors of ill health, and now tour promoter Andrew McManus has opened up about Houston's breathing difficulties, pinpointing her tobacco habit as the cause.
Whitney Houston's explore advocate has offered a rationalization for the singer's hesitating voice - the star declines to stop smoking.
McManus enlightens, "Whitney smokes. She will not take any imports. She just will not. It is what it is. She's comfortable with the show she's performing. She knows she's not hitting every note like she used to. But it's value for money, its Whitney Houston warts and all."
"It's an motivating loom. Here I am being forceful in trying to protect her and she said, 'I love you for it but let it go. I can only give my best, if that's not good enough, so be it. I'm comfortable in my own skin.'"
