Whitney Houston just came back but she needs a break already.? If you recall, several fans walked out of her Australian concert back in February, citing that the 46 year old singer just wasn’t ready to perform.

Apparently Whitney now feels the same and has postponed the start of her European tour:

According to the AccessAtlanta:

Citing an upper respiratory infection, the iconic singer has postponed her Tuesday Paris show, and will instead kick off the tour with the show that had been scheduled to follow in Manchester, England this Thursday, the Associated Press reports.

A rep for the singer tells the AP that Houston “deeply regrets having been forced to postpone the show.” The singer plans to reschedule the concert, according to the news agency.

While Houston denies it, there have been several reports that she’s fallen back into her old drug habits. The National Enquirer even reported that she’s back in rehab but again…. her people deny it.

The star’s rep insisted Houston’s breathing difficulties were caused by smoking cigarettes, and denied allegations she had returned to using crack cocaine.

*sigh* Get well soon Whitney. The world is waiting…
