NICOLE RICHIE GUEST-STARS ON AN ALL-NEW "MADtv" SATURDAY, JANUARY 22, ON FOX

Performance from Female Foursome "The Donnas" and "American Idol" Parody Featured

THE SIMPLE LIFE's Nicole Richie shines when she lampoons daytime talker and actress "Kelly Ripa" in a "Garnier Nutrisse" shampoo commercial alongside a rich and radiant "Sarah Jessica Parker" (Nicole Parker) and dye-dripping "Vienetta Jones" (Daniele Gaither) on MADtv Saturday, Jan. 22 (11:00 PM-Midnight ET/PT) on FOX.

Other highlights in Saturday's episode include femme fatales "The Donnas" staying up late to perform "Don't Want To Know" from their new release "Gold Medal" as well as a parody of Kelly Clarkson's new music video "Since U Been Gone" titled "Since We Were On." In this not-so-harmonious sketch, "Kelly Clarkson" (Nicole Parker) sings next to other "American Idol" winners "Ruben Studdard" (Aries Spears) and "Fantasia Barrino" (Daniele Gaither) while runner-ups "Justin Guarini" (Jordan Peele), "Clay Aiken" (Ron Pederson), "Diana DeGarmo" (Paul Vogt) and, of course, "William Hung" (Bobby Lee) contribute. When these past "American Idols" finish describing how things have changed since they appeared on AMERICAN IDOL, "Simon Cowell" (Michael McDonald) chimes in to make one final judgment.

MADtv, in its 10th season, is a production of QDe. The executive producers are David Salzman, Quincy Jones and Dick Blasucci.
