Khloe Kardashian is planning a raunchy bachelorette party for sister Kim. 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.

"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," Khloe - who married basketball star Lamar Odom in September 2009 - told E! Online.

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."
