Media Movment

I watched this video and I wanna know if you guys think the "feud" between Mariah and Nicki is talkd about so much and used to get people to watch American Idol because they are female? I picked this because I have seen alot about this "feud' between these two women on t.v.
Also what do you guys think of the term "Diva" do you thnk its bad,good and over used in the media.
