An X17 source confirms that Khloe Kardashian's court-ordered trip to prison has ended after a short 173-minute stay behind bars. She's already been released from Lynwood Prison.

Of course, that's still over twice as long as Nicole Richie's hilariously short 82-minute stay last year - wow, they really threw the book at Khloe, huh?
