Will Kim Kardashian Continue Using Kanye West's Last Name After Divorce? Last month, celebrity divorce lawyer Atty. Laura Wasser formally submitted the divorce papers of the estranged couple, Kim Kardashian and Kanye West. In the new details of their divorce filings, it has been reported that their separation was due to "irreconcilable differences." Aside from the divorce drama, fans began to question whether Kim will still use West as her last name. Fortunately, a source finally shed some light and answered the lingering question. In a statement to E! News, an unnamed source revealed that the "Keeping Up With The Kardashians" star remains undecided whether or not she will remove West from her branding.
