There is one phrase that former WWE champion John Cena might hear soon and that’s "You’re fired". And no it won’t be Vince McMahon saying that but Donald Trump! AOL-owned TMZ.COM spilled the beans on some of the participants who will be on NBC’s ‘Celebrity Apprentice’. That’s right, the injured John Cena is already filming the show as TMZ.COM cameras spotted many of the celebs selling hot dogs on the streets of New York as part of a challenge. Cena joins Omarosa, Lennox Lewis, Gene Simmons, Stephen Baldwin, Carol Alt, Vinny Pastore, UFC’s Tito Ortiz and others in this new season of The Apprentice. Donald Trump is, as always, running the show. With Cena out for at least six to eight months, it gives him a great opportunity to get involved in other projects. And we all know that the Donald is a big WWE fan so having Cena on his show is certainly a big acquisition so to speak. The Celebrity Apprentice will air in mid-season on NBC.
