Khloe Kardashian, Kim's lil' sis, will surrender Friday to begin serving 30 days in the slammer for a probation violation after a DUI.

Kim K, who might have trouble getting her major asset in a 12x8 cell, is now speaking out, saying, "Khloe is ready and willing to serve out her sentence, no matter how long and where, and have this resolved."

And Kim says, "I urge people to learn from the mistakes of others. Please drink responsibly and it's never acceptable to drink and drive!"
