Gearing up to the production of "The Celebrity Apprentice" season 5 which will begin next week, an insider has leaked the identity of two contestants. According to EW, actress/model Cheryl Tiegs and race car driver Marco Andretti have signed up to join the new installment of the reality show.
64-year-old Tiegs was featured three times on the cover of Sports Illustrated Swimsuit Issue during 1970-1983. She last took part in a reality show when she judged ABC's "True Beauty" in 2009. Andretti, meanwhile, is the 24-year-old son of former IndyCar World Series champ Michael Andretti and the grandson of racing legend Mario Andretti.
In addition to these two names which came from a quite reliable source, previous reports have mentioned other celebs who may join the fifth season of "The Apprentice" spin-off. The rumored cast members are Teresa Giudice of "The Real Housewives of New Jersey" and Aubrey O'Day, but NBC has not confirmed either of them.
