According to TMZ, the Keeping Up With The Kardashians star made the move this morning, citing "irreconcilable differences" as her reason.
Despite only being married for 72 days, it is thought Kimmy will not seek an annulment, with the website stating the date of separation is listed as today, 31st October 2011.
Ryan Seacrest has since confirmed the news on Twitter, posting: "Yes @KimKardashian is filing for divorce this morning. I touched base with her, getting a statement in just a few mins.”
Kim's marriage to Humphries was previously branded a sham by a source, who claimed she married Kris just for the cameras and originally wanted to wed New York Knicks star Danilo Gallinari - but he refused.
Kardashian recently addressed reports that her marriage to Kris was on the rocks, telling People: "Something I really prepared Kris for [was] to let him know that no matter what we do, there's going to be rumours. It used to really upset me and now I don't even think about it."
The pair have been dogged by split accusations after Humphries was spotted without his wedding ring.
