“Keeping Up With the Kardashians” star Khloe Kardashian served 173 minutes of her 30 day jail sentence, and Kim’s little sis reported that her time in solitary confinement definitely wasn’t boring.

“There was a bomb threat,” Khloe told Ryan Seacrest on Monday. “They put me in solitary confinement and the warden came down to talk to me and said, ‘You’re the one causing all the problems here. … There are all these bomb threats, and we think they’re because of you.’”

Khloe checked in Friday to the Century Regional Detention Facility at Los Angeles County’s women’s jail in Lynwood, California, which boasts Paris Hilton and Nicole Richie as former celebrity inmates. She was sentenced to serve time for failing to meet the terms of her probation for her DUI arrest and was releasedearly due to overcrowding and because she posed a threat to other inmates, she said.

Before the youngest of the Kardashian sisters checked into jail, Kim talked to Jimmy Kimmel about how her family was dealing with Khloe’s impending incarceration.

Well now we know for sure who the bad Kardashian sister is, and amazingly it’s not the big-assed tramp with the sex tape! Khloe Kardashian was not only busted for a DUI (Seriously, how the eff did we not know this?!) on March 4, 2007, but she then went and violated her probation. The poor rich girl didn’t want to pick up trash on the highway or attend her alcohol education program, so she’s going to jail for 30 days! Hm – trash or jail, which is worse? She’s more familiar with garbage (her reality show, for starters) so she should have just stuck with what she knows! Now she’s stuck with 30 days in jail, of which she’ll probably serve 30 seconds, just like Lindsay and Nicole. Good luck Khloe!

Her sister Kim had something to say about the whole thing, obviously, other than “watch our TV show!”

I have been getting asked all day if Khloe is going to jail. I know my fans rely on coming to my blog for the truth… Khloe wants you to know she was sentenced to go to jail in regards to her one DUI case last year. 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!
