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.
