Apparently, she couldn't keep the secret for long. Five minutes later, she spilled the beans:
The couple played on the same team, along with three of West's relatives. The Kardashian-Jenner team included Kris Jenner, her mother Mary Jo "M.J." Campbell, and daughters Khloe Kardashian and Kendall Jenner. Family friend Jonathan Cheban was also at the taping, though E! News reported it was unclear which team he was on.
West's appearance on the show was the culmination of a lifelong dream for him, according to a Snapchat video Kim Kardashian posted before the taping.
"If you guys don't know, Kanye and I are the biggest fans of 'Family Feud,'" she said in the post. "Kanye said he's waited his whole life for this moment: 'Family Feud.' We're playing against the Kardashian Jenners vs. the Wests. And I have a really good feeling about this, that we're going to win."
However, she didn't do well on at least one question, according to an insider quoted by Page Six.
At one point, host Steve Harvey reportedly asked Kardashian, "What is a body part that you're constantly bumping into things with?"
"Her reply was 'my butt,' and the answer resulted in a zero," the insider said.
The Wests vs. Kardashian-Jenners episode of "Celebrity Family Feud" will air later this year.
Cosmopolitan notes that while West has never appeared on "Family Feud," Kim Kardashian and the Kardashian-Jenner family faced off against Deion Sanders' family in 2008. In addition, the family played itself in a Mad TV skit years ago in which they competed against cast members portraying various Disney Channel stars.
