Houston’s smoking habit spoils her Oz shows

London (ANI): Whitney Houston is having trouble singing at her concerts in Australia because of her smoking habit.The singer's voice apparently cracked during her shows in both Brisbane and Sydney. She has received flake from critics and fans, who even walked out from her shows.

Now, tour promoter Andrew McManus has revealed Houston is having breathing difficulties due to her tobacco habit. "Whitney smokes. God bless her, I can't tell her not to. She will not take any substances. She just will not. It is what it is," the Daily Express quoted McManus as saying.

He added: “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, it's Whitney Houston warts and all."I talked to her after the Sydney show. I told her I have her back but she said, ''If the good Lord wants me to be attacked and ridiculed that''s the road I have to go down."

"It's an interesting approach. Here I am being aggressive 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."
