Kim Kardashian's wedding planning is well underway, but it's her mom, Kris Jenner, who's keeping things in line.
"I have no idea what's going on," Khloe told Us Weekly on Wednesday at Hpnotiq Harmonie's Launch Event in New York. "[But] I've seen how much my mom has been doing, and I don't know how my mom does it! Kim should be kissing the ground that my mom walks on. It's amazing."
"But I am doing the bachelorette party," Khloe, 27, exclaimed. "And that's going to be payback!"
Before Khloe married Lamar Odom in Sept. 2009, Kim was in charge of her sister's last fete as a single gal. It "was very embarrassing," Khloe said. "It was everything penis themed! Kim is not like that. She's very uncomfortable with that so we're going to embarrass her."
But Kourtney, 32, isn't helping Khloe plot her raunchy revenge. "She's not on my same page," Khloe explained. "She's pulling the mom card. I'm like what's happening to you! I'm going all out though… You can only imagine what I'm going to do for her. She's going to hate me!"
Kim, 30, and Kris Humphries, 26, got engaged in May after less than six months of dating. Khloe said that she still doesn't know the NBA star as well as she'd like to. "We definitely need more bonding time," she said. "I just feel like we're so busy."
As for Kim's actual wedding, Khloe predicts it's going to be over-the-top. "It's going to be royal wedding number two," she told E! News in May. "I could only imagine Kim having the hugest wedding."
