Khloe Kardashian is already happily married to her hubby Lamar Odom for about two years, but now her big sis Kim Kardashian is getting ready to tie the knot, reportedly by the end of the summer!  We've already heard that Kim's nuptials to Kris Humphries are going to be an extravagant affair, and Khloe has revealed to Us Weekly just how hard her mom Kris Jenner is working on planning the event and her plans for the bachelorette party

When discussing Kim's bachelorette party, Khloe said she was planning her sister's last night of freedom and that Kim can expect some payback for the party she threw Khloe before she got married in 2009.  "[My bachelorette party] was very embarrassing," Khloe recalled. "It was everything penis themed!  Kim is not like that.  She's very uncomfortable with that so we're going to embarrass her!"

Unfortunately for Khloe, though, she won't be getting any help from her other sister Kourtney Kardashian.  "She's not on my same page," Khloe said. "She's pulling the mom card.  I'm like, 'Whats happening to you!?'  I'm going all out can only imagine what I'm going to do to her!  She's going to hate me."

While Khloe is planning the bachelorette party, she says she has nothing to do with the planning of the actual wedding, although she did join Kim last week while she shopped for wedding dresses at Vera Wang.  Although Khloe is not involved, she realizes how much work is going into the event.  "I've seen how much my mom's been doing, and I don't know how my mom does it," she explained. "Kim should be kissing the ground that my mom walks on.  It's amazing."

What do you think Khloe will do for Kim's Bachelorette party?  We can't wait to find out!
