Heidi Pratt has hit a high note. The Hills star, 22, has been selected to perform during the 2009 Miss Universe Pageant telecast next month, Usmagazine.com has learned.

She will belt out "Turn Ya Head" off her upcoming debut album, Unleashed, during the Aug. 23 show. Access Hollywood reports that Celebrity Apprentice star Claudia Jordan, Flo Rida, Kelly Rowland and dancer David Guetta also will take the stage.

Celebrity choreographer Michael Schwandt will be working with Montag to prepare for her performance.

Despite the new Miss Universe gig, Pratt's singing hasn't been embraced by fans. Shortly after debuting her first single and video, "Higher," in 2008, online critics slammed her on the web.

"Makes me feel uncontrollably ill," "beyond pathetic," and "the crappiest video I have ever seen" were among the comments posted on Usmagazine.com.

At the time, Montag told Us, "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."
