As you likely saw, the latest season of American Idol debuted this week with hopefuls from around the globe looking to become the "next big thing" in pop music. Something equally as entertaining, if not more so, also debuted on the program: Nicki Minaj and Mariah Carey's feud.

As you'll see in the above clip, their banter would quickly turn from playful to argumentative, though many times the two would mesh. For example, how did neither of them laugh during the whole faux-British accent thing? Ridiculous.
