During WWE "Main Event", the commentators were discussing "Total Divas" and stated that Total Divas has officially been renewed for a second season starting 2014.
No official press release yet from E! or WWE, however it seems very likely that this would be the case given that "Total Divas" ratings are incredibly strong on "E!" and WWE is very happy with the show.
I'd expect both sides to announce a new season very soon formally.
