Nicole Kidman To Appear On Project Runway: All-Star Challenge 8/20

E!Online reports that Nicole Kidman is to appear on ‘Project Runway: All Star Challenge'. The stage and screen star will make a guest appearance on a ‘design special' episode of the reality show.

Nicole will join host Heidi Klum, judges Michael Kors and Nina Garcia and the show's style mentor Tim Gunn for the two-hour long special episode. The program - which will air on Thursday August 20th - will feature eight stars from previous seasons returning to their sewing machines for a one-off show immediately before the return of the highly-anticipated sixth series.

Season two contestants Daniel Vosovic and Santino Rice, season three's Uli Herzner, Jeffrey Sebelia and Mychael Knight and series four favorites Chris March and Sweet P will return to the TV screen alongside Korto Momolu, who was a contestant on the last series.

Kidman most recently starred in Baz Luhrmann's "Australia." She will next appear in Rob Marshall's musical "Nine" for the Weinstein Co. that is hitting screens in November 2009. 

Nine is a musical with a book by Arthur Kopit and music and lyrics by Maury Yeston and is based off of Fredrico Fellini's movie 8 1/2. The play tells the story of a young film maker living in Venice trying to juggle all of the women in his life.
