The 30-year-old socialite is set to marry basketball star Kris Humphries later this year and sibling Khloe wants to make her last party as a single woman as tacky as possible because she knows she`ll hate it.

Khloe - who married basketball star Lamar Odom in September 2009 - told E! Online: "I want to do it as bad as possible because she`s so uncomfortable by it, and it`s funny. For my bachelorette party, it was so over the top, so I want to be as annoying as possible with the bachelorette thing."

While she can`t wait for her sister to get married, Khloe is unsure if Kim will start trying for a baby straight away.

The 26-year-old reality TV star - who has made no secret of her desire to start a family - said:

"I don`t know. I really don`t. If Kim does have a kid soon, I think she`s gonna have to slow down so much. So I just don`t know if she`s ready to slow down that much."
