Last night Nicki sat down with fellow native NY'er Jimmy Kimmel, where she dished on everything from why she walked off the "American idol" set, to who would win in a fist fight between her and Mariah Carey, she explained her love of monikers, and how she was almost arrested in Dubai. Nicki was a lil tight lipped on the secrecy of the language she shares with her "barbz."...."CF's" anyone? Watch the full interview and the LIVE performance below.
