Whitney: Health Concerns?

As Whitney Houston continues her comeback bid, but keeps giving shaky performances on her concert tour, many are asking questions about the pop icon's physical health.

Whitney was away from performing for years, suffering through well-documented drug problems in addition to a drama-plagued tabloid feeding family life with Bobby Brown. And when she finally made her comeback attempt last year, millions of fans were rooting for her to rise back to the top of the pop charts.

But with her first public performances fans immediately noticed the voice wasn't what it used to be, in fact she seemed to be struggling to keep her breath and sing on key at all, and not even coming near the high notes and vocal power she used to show.

And as her world tour goes on, her most recent show in Australia became a scandal down under, as her terrible performance sent ticket buyers into an outrage, a shame considering how rarely Australian fans get to come out for their favorite artists.

That latest in a long string of shaky performances is bringing questions about Whitney's health, but her reps insist to potential concert ticket buyers that Whitney is just fine and not in "fragile" health as the tabloids have reported.

Whitney Houston has sparked fresh fears for her health after appearing at a concert in Australia looking exhausted as she struggled through her set. The singer, who kicked off her first world tour in a decade in December 2009 became the subject of a National Enquirer report last week, alleging Houston has been in a fragile state. Houston's representative blasted the claims, insisting rumors she is battling a mystery illness are "ridiculous."
