Flo-Rida, Kelly Rowland (w David Guetta) and Heidi Montag to perform during the Miss Universe telecast on Aug. 23

Heidi Pratt is heading back to NBC.

The “Hills” blonde, who doubles as an aspiring pop star, will perform during the 2009 Miss Universe Pageant telecast next month, Access Hollywood can exclusively reveal.

Heidi treated fans to snippets of her singing while in the Costa Rican jungle earlier this summer on “I’m A Celebrity… Get Me Out Of Here!” and viewers of the Miss Universe Pageant will get to check out what Heidi sounds like on the big stage on August 23.

Heidi will perform the song “Turn Ya Head” off her debut album, “Unleashed,” which came out in July.

Other stars who are set to take the stage at the pageant, which will be co-hosted by Access‘ own Billy Bush and “Celebrity Apprentice” star Claudia Jordan, include Flo Rida, Kelly Rowland and dance kingpin David Guetta.

Flo Rida will perform “Right Round” and “Jump” as a two-song medley during the pageant’s swimsuit competition.

Kelly and David will perform the song, “When Love Takes Over” together during the evening gown portion of competition.

The Miss Universe 2009 Pageant airs August 23 at 9 PM on NBC.
