WHITNEY BLIMPS OUT!

Troubled singer plumps out to human zeppelin proportions as WHITNEY HOUSTON's weight  spirals out of control!

As this astonishing photo from a May 27 concert in Germany reveals, the troubled Grammy winner has packed on at least 20 pounds recently.

While experts believe some of the weight gain has been caused by steroid injections or prednisone treatments to treat a nagging respiratory infection, insiders say Whitney's been "pigging out" on room service and fast food during her "Nothing But Love" European tour.

"She's ballooned to 175 pounds.

"AND there's no sign of slowing down," added a source.
