Khlo Kardashian is reportedly concerned that her sister Kim's new romance with Kanye West will harm her in her divorce proceedings.

The 31-year-old reality star is currently embroiled in a split from estranged husband Kris Humphries following their 72-day marriage.

But a source told RadarOnline that Khlo wants her sibling to stay off of the dating scene for a while.

"Khlo just wishes that Kim wouldn't even get involved with anyone for at least a year," the insider said.

"Kim isn't even divorced yet and Khlo is extremely worried that Kris is going to try and attempt to use her new relationship as ammunition to score a bigger settlement.

"Khlo doesn't want her sister to get hurt again and she is extremely concerned about cheating allegations that have been made against Kanye in the past. Kim is extremely vulnerable, and the last thing she needs is to have her heart broken."

Kris is reportedly seeking to find out if Kim spent any money on Kanye during their marriage as under California law he would be entitled to any money back that his spouse spent on an alleged lover.
