Things took a dramatic turn during the Season 18 premiere of "Keeping Up With The Kardashians." Kourtney Kardashian and Kim Kardashian, aged 40 and 39 respectively, got into a physical altercation after an argument about work ethic.
It all began when Kourtney insinuated that she no longer wants to be part of the show. Kourtney found herself struggling to get back at work after spending a month in Italy with her children.
