For reasons unknown to anyone alive, The Hills star Heidi Montag has been selected to perform during the 2009 Miss Universe Pageant telecast next month.

Talk about hitting a low note in the history of pageants and music.

The god-awful "singer" will belt out "Turn Ya Head" off her upcoming debut record, Unleashed, during the August 23 broadcast. Across America and the world, remote control MUTE buttons will be punished with unprecedented force.

Access Hollywood reports that Celebrity Apprentice star Claudia Jordan, Flo Rida, Kelly Rowland and DJ David Guetta also will take the stage that night.

But the true star of the evening will be horsey-face herself ...

Despite the new Miss Universe gig, it would be the understatement of the year to say that Mrs. Spencer Pratt's singing hasn't been embraced by the public.

Shortly after debuting her first single and video, "Higher," in 2008, online critics slammed her on the web. At least the ones that weren't doubled over laughing.

"Excuse me while I go vomit," "WTF is she serious," "LOL WUTTTT" and "give me a f**king break" were among the responses by The Hollywood Gossip readers.

Montag said, "I cried myself to sleep that first night after my video came out. I am just a 21-year-old from a small town in Colorado trying to follow her dreams."

With the fake boobs, nose and lips to prove it, too.

She hasn't been deterred by fan reaction, or by having no talent whatsoever, as she's subsequently dropped the singles "No More," "Overdosin'" and "Black Out."

They all sound similar and are equally terrible.
