Ending weeks of speculation, ABC president Paul Lee announced the cast of its upcoming Dancing With the Stars all-star edition during a session this morning at the TV Critics Association press tour in Beverly Hills.

The former DWtS participants who will be lacing up their dancing shoes for a return engagement are:

* Former Baywatch babe Pamela Anderson

* One-time boy-band star Joey Fatone

* Ex-Bachelor star Melissa Rycroft

* Former Cheers star Kirstie Alley

* Olympian Shawn Johnson

* Ex-98 Degrees singer Drew Lachey

* Hunky actor Gilles Marini

* Unwed teen mom/reality TV personality Bristol Palin

* NFL great Emmitt Smith

* Speed racer Helio Castroneves

* Olympic speed skater Apolo Anton Ohno

In an added twist, one final spot will be filled by a contestant chosen by viewer votes, with the three contenders being former Queer Eye guy Carson Kressley and one-time Disney Channel stars Kyle Massey and Sabrina Bryan.

The all-star edition of Dancing With the Stars: All-Stars will premiere September 24 on ABC and CTV.
