The ‘Celebrity Big Brother’ cast is a ‘Dancing with the Stars’ and ‘Celebrity Apprentice’ alum minefield

Will there be a “Dancing with the Stars” alliance versus a “Celebrity Apprentice” alliance on “Celebrity Big Brother”? Of the 11 houseguests entering the “Celebrity Big Brother” house, nine of them have either been on “Dancing with the Stars” or “Celebrity Apprentice.” Which begs the question: Why is CBS taking ABC’s and NBC’s sloppy seconds? Did CBS over-correct in not wanting to pluck from its own reality shows? Or is Julie Chen just a huge “Dancing” and “Apprentice” fan?

The two non-“Dancing” and “Apprentice” alums are Miss Colombia 2014 Ariadna Gutierrez and E! personality Ross Mathews, who appeared on “Celebrity Fit Club” 10 years ago. Everyone else is a former wannabe hoofer or Donald Trump pupil. Even weirder: Two people from each show were on the same season together. Check them out below.

“Dancing with the Stars” alums
Shannon Elizabeth: The “American Pie” star and partner Derek Hough finished in sixth place on Season 6. (Fun fact: This was one of three times six-time champ Hough finished lower than fourth during his 17 seasons; it’s tied with his run with Marilu Henner for his lowest finish.) Elizabeth and Hough dated during the season, so she’s probably not opposed to a showmance on “CBB.”

Chuck Liddell: The UFC champ and partner Anna Trebunskaya finished in 11th place on Season 9.

James Maslow: The Big Time Rush singer and partner Peta Murgatroyd placed fourth on Season 18.

Marissa Jaret Winokur: The Tony-winning “Hairspray” star and partner Tony Dovolani finished two spots higher than Elizabeth and Hough, in fourth, on Season 6.

Metta World Peace: The Artist Formerly Known as Ron Artest and partner Murgatroyd were the first pair eliminated on Season 13.

“Celebrity Apprentice” alums
Brandi Glanville: The former “Real Housewives of Beverly Hills” star placed fourth on Season 7. She is the only houseguest with “Big Brother” experience, having finished 11th the U.K. version of “CBB” last summer.

Omarosa Manigault: Trump’s disgraced former White House aide became one of reality TV’s most notorious villains when she finished eighth on the first season of “The Apprentice.” She later finished sixth on the first installment of “Celebrity Apprentice.”

Keshia Knight Pulliam: The erstwhile Rudy Huxtable was the first one fired on Season 7 after she, as project manager, led her team, which included Glanville, to a loss. Knight Pulliam was also the first cut on ABC’s short-lived celebrity diving series “Splash,” so maybe reality shows aren’t really her thing.

Mark McGrath: The Sugar Ray frontman placed 10th on Season 4.

Will a “Dancing” or “Apprentice” alum prevail? Or will Guitterez and Mathews band together to take them down?

“Celebrity Big Brother,” which runs for three weeks, premieres Wednesday, Feb. 7 at 8/7c on CBS.
