"American Idol" contestants find out who is generating the biggest buzz, Nicki Minaj and Mariah Carey. Minaj walked off the set after fellow judges Keith Urban, Randy Jackson and Carey labelled contestant Summer Cunningham a country singer. "Maybe I should just get the (bleep) off of the panel," Minaj erupted and then did just that. Jackson's comeback: "I was only trying to help Summer, with my 30-years of industry experience." The irony is that Minaj had no trouble dropping her branding on contestant Naomi Morris, whom she renamed "Omi." Ah yes, Idol is fun again.
