Piers Morgan is still basking in the glory of seeing Omarosa fired, in the largest defeat in "Apprentice" history, as the remaining five celebrities race against the clock to invent and sell a new sandwich for Quiznos on this week's NBC's "The Celebrity Apprentice" Thursday, March 13 (9-10 p.m. ET/PT).

Both teams model their sandwiches after their celebrity image as they scramble to bring in customers off the streets and make the most sales. As the competition progresses, one team runs out of sandwiches, and the other team struggles with customers. In the boardroom, the decisions are becoming more difficult for Donald Trump as he sends one of the last celebrities packing.

Donald Trump's eyes and ears on the task are his daughter Ivanka Trump and Daryl Roth.

Last week's competition saw the seven celebrities battling it out in a New York City art gallery as they selected artists, displayed their work and sold the pieces in a shared gallery space. The project managers, Piers Morgan and Omarosa, were competing to make the most sales. In a stunning triumph, Piers took great pleasure in seeing his season long nemesis, Omarosa, pack her bags and leave the boardroom.

Tiffany Fallon, Nadia Comaneci, Gene Simmons, Jennie Finch, Nely Galan, Marilu Henner, Tito Ortiz, and Omarosa are the eight celebrities who have been fired by Donald Trump to date. Vinny Pastore resigned when the competition took an ugly turn. The remaining celebrities competing for charity are: Trace Adkins, Carol Alt, Stephen Baldwin, Lennox Lewis and Piers Morgan.

"The Celebrity Apprentice" is produced by Mark Burnett Productions in association with Trump Productions LLC. Mark Burnett, Donald Trump are executive producers, Eden Gaha and Page Feldman are co-executive producers.
