The fifth season of NBC’s The Celebrity Apprentice (also known as The Best Show of All-Time) will begin filming next week, and an insider close to the production has revealed the identity of two of the contestants vying for Donald Trump’s affection. Three-time Sports Illustrated Swimsuit Issue cover girl Cheryl Tiegs will be part of the cast, as will race car driver Marco Andretti.

The 64-year-old Tiegs’ reality show experience dates back to 1978 when she competed alongside Gabe Kaplan, Parker Stevenson, and Toni Tennille on the ABC team for Battle of the Network Stars. She also appeared as a judge on the first season of ABC’s True Beauty in 2009. The 24-year-old Andretti is the grandson of racing legend Mario Andretti, and the son of former IndyCar World Series champ Michael Andretti. He may have a leg up on the competition in the marketing/branding department, having already displayed an impressive ability to wedge an obscene amount of corporate logos on his racing outfit.

The two stars will follow in the footsteps of such luminaries as Gary Busey, Rod Blagojevich, and that woman who used to open briefcases on Deal or No Deal, as Trump and Co. promise to once again raise ridiculous amounts of money for charity while offering up non-stop hilarity along the way. Season 5 of The Celebrity Apprentice (and the 12th installment in the Apprentice franchise) will premiere in early 2012.
