Kim Kardashian annulled so that he is able to talk openly about it.
Kim filed for divorce from Kris several weeks ago on October 31 - when they had been married for just 72 days - but he filed annulment papers on Wednesday.
And now it has been claimed that by doing so he hopes to make his pre-nuptial confidentiality agreement null and void.
The Daily Mail quoted a source as saying: "The confidentiality aspect of the pre-nup is extensive and was created just in case things went bad, neither Kim nor Kris could discuss their relationship to the media.
"Kris wants to be able to talk about the relationship without fear of being sued... Kris is getting excellent legal advice. If the judge annuls the marriage, they were never legally married, and the pre-nup at that point is really moot."
