Kim Kardashian's sister wants her to "cringe" at her bachelorette party.

Khloe Kardashian hated the pre-wedding Celebration her siblings threw for her ahead of her nuptials with Lamar Odom in September 2009 and so is planning her revenge by embarrassing the brunette beauty - who recently got engaged to basketball player Kris Humphries - when they mark the end of her single days.

Khloe said: "I had the worst bachelorette party. Like, it wasn't sexy at all, so I might just do a payback for Kim... Because Kim does not like what she gave me, like penis straws and a little go-go dancer. Kim would cringe if I did that for her, so I might do that just to see what happens."

Khloe - who married Lamar after just one month of dating - also admitted she and sister Kourtney have not decided whether to buy engagement gifts for Kim and Kris.

She told E! News: "Kourtney asked me the other day. She's like, 'Do we buy her an engagement gift?'. I'm like, 'No one bought me an engagement gift!' What is that about?"

The 26-year-old socialite walked down the aisle in a gown created by family friend Vera Wang and is hopeful Kim will choose the same designer.

She said: "She did mine, so I hope she does. Just because I love her, and I feel like when you think of weddings, you think of Vera Wang. I think it would be a perfect fit."
