The identities of those participating in The Apprentice's upcoming celebrity edition have begun to emerge and -- surprise, surprise -- they're not as impressive as the names Donald Trump previously boasted about.

Supermodel Carol Alt; actor Stephen Baldwin; wrestler John Cena; actress Marilu Henner; professional boxer Lennox Lewis; mixed martial arts fighter Tito Ortiz; former The Sopranos actor Vincent Pastore; former KISS frontman Gene Simmons; and The Apprentice first-season contestant Omarosa Manigault-Stallworth will all be participating in The Apprentice's celebrity edition, reported Friday.

In addition, TMZ also filmed several of the aforementioned celebrities -- including Lewis, Simmons, Pastore and Baldwin -- selling hot dogs on the streets of New York during what appeaed to be a The Apprentice task assignment.

Several of the participants in The Apprentice's celebrity installment should be familiar to reality television viewers.

Baldwin competed on ABC's Celebrity Mole Hawaii and Celebrity Mole Yucatan, hosted Sci Fi Channel's Scare Tactics, and most recently appeared as a contestant on CMT's Ty Murray's Celebrity Bull Riding Challenge;  Pastore was scheduled to appear as a Dancing with the Stars' fourth-season celebrity participant before backing out of the competition due to his age and fragile state; and Simmons stars in Gene Simmons Family Jewels, the third season of which was recently ordered by A&E.

After being fired by The Donald during The Apprentice's first season, Manigault-Stallworth also appeared on The Surreal Life's fifth season and participated in a Fear Factor reality-stars special.  She also made a cameo on I Love New York's first season last spring on VH1.

Two months ago, Trump claimed to be in talks Britney Spears and Paris Hilton and signed an "eye-popping list" of celebrities to compete in The Apprentice's celebrity-themed seventh edition.

According to Trump, The Apprentice's celebrity edition -- which was announced after a two-month public feud that began with NBC leaving one-time smash-hit but now ratings-challenged reality series off its 2007-2008 schedule and Trump responding by publicly proclaiming that he was "moving on" and quitting the show -- was set to include Jim Cramer, Carmen Electra, Jeff Gordon, Tony Hawk, Naomi Judd, George Foreman, Danica Patrick, Joan Rivers, Pete Rose, Kimora Lee Simmons, and Omarosa.

However two days after Trump gushed about his "eye-popping" list of participants for the charity competition, his publicist denied the report.
