Kim's stepdad made the revelation to Oprah Winfrey, in the second part of Lady O's interview with the entire Kardashian-Jenner clan.
"What do you wish you could take back?" Oprah asked the former Olympian as he sat with wife Kris Jenner.
"The whole wedding thing," Bruce said, looking more than a little embarrassed. "We went so overboard on it."
But did he think it would work?
"I was hoping it would work," is as far as Jenner would commit.
You can see the entire interview on Oprah's Next Chapter, Sunday night on OWN.
