Kanye West, 43, is fully aware that Kim Kardashian, 40, filed for divorce from him last month, but he “doesn’t believe” she is serious about it. “Kanye hasn’t filed a response to Kim’s divorce filing because he still doesn’t accept that Kim will see the divorce through to completion,” a source EXCLUSIVELY told HollywoodLife. “He knows how Kim is and he knows that she does not want to do this.”
