Donald Trump is again joined in New York by a group of 16 celebrities who compete in business challenges to raise money for their favorite charities. Previous winners -- including Bret Michaels, John Rich, Arsenio Hall and Trace Adkins -- return to help advise the competing teams as they complete their tasks and weigh-in in the board room. This season's star-studded cast -- including baseball player Johnny Damon, comic Gilbert Gottfried, actress Vivica A. Fox and author Brandi Glanville -- promises to bring generous donations to many worthy causes.
