Khloe KardashianKim Kardashian’s younger sister Khloe Kardashian is set to belatedly join last year’s key celebrity socialite trend: spending time in jail.

The socialite is set to surrender herself to authorities on Friday after admitting to violating her probation conditions earlier this month: Khloe was placed on a 36 month probation after a DUI offence in March 2007 but failed to comply with the community service and alcohol education elements of the deal.

She has been sentenced to 30 days in jail for the violation but, due to over-crowding in women’s prisons around Los Angeles, she is expected to serve less time than that: Nicole Richie’s four day sentence was reduced to just 82 minutes and Lindsay Lohan served just 84 minutes of her day of jail time.

Speaking about her sister’s pending jail time, Kim Kardashian wrote on her blog yesterday: “Khloe is ready and willing to serve out her sentence, no matter how long and where, and have this resolved.

“I urge people to learn from the mistakes of others. Please drink responsibly and it’s never acceptable to drink and drive!”
