"It's her own fault"

KIM KARDASHIAN's sister KHLOE deserves her jail sentence for violating probation on a drink driving charge, according to the girls' mother KRIS.

The 24-year-old has been sentenced to serve three days in Los Angeles County Jail after failing to complete roadside clean-up duty and alcohol education classes following her arrest in March 2007.

But the matriarchal star of reality TV show Keeping up With The Kardashians isn't offering her daughter any sympathy, admitting, "There's lots of things I could be sitting here saying, and making excuses for my daughter.

"To me, she's still 15. At this point, I'm up against a wall. What am I going to do? Scream at her? I've done all that."

Khloe's more famous older sibling Kim, 27, has meanwhile posted a blog claiming her sister is "ready and willing to serve out her sentence," which will reportedly begin on Friday.

The older Kardashian hopes her sister's misfortunes will help guide other teenagers: "I urge people to learn from the mistakes of others. Please drink responsibly and it's never acceptable to drink and drive!"
