I agree Lenny Kravitz would have been amazing. The combination would have been perfect. More like the banter and good feeling The Voice judges offer. Pop/R&B diva (Mariah), Keith for the people who cares about country music and a rocker (Lenny). Specially cos Lenny has such a long career too. The Nicki thing is just... well they were sure waiting for ratings (producers) and it seems they are having it for sure. Congrats :)

ps: people trying to make excuses about nicki minaj... please be real and know your place, people are working on American Idol, if you don´t know to handle yourself stay at home and don´t search for big contracts. Did she think she was talking with irrelevant rappers at her house?
