is opening up – just a little – about why she's ending
her 72-day marriage to Kris Humphries.
"I hope everyone understands this was not an easy decision," she says in a statement to E!
, which airs her reality shows. "I had hoped this marriage was forever, but sometimes things don't work out as planned. We remain friends and wish each other the best."
Kardashian, 31, cited "irreconcilable differences" in her Los Angeles Superior Court filing on Monday, saying the couple have a prenuptial agreement and asking the court to deny spousal support to Humphries.
"All of us at E! are surprised and saddened by this news, and we send our support to Kim and Kris at this difficult time," the network that airs the family's reality shows said in a statement.
"The Kardashians have always been uniquely open with all aspects of their lives from joyous events to intimate moments to heartbreaking transitions. E! will continue to share the fascinating real lives and larger-than-life existence of this close-knit family."
