DIANNE BUTLER OUT OF THE BOX
HERE’S what we know so far: Mariah Carey and Nicki Minaj hate each other. That’s not just for show, what we’re going to see up there. Of the 256 who make it to Hollywood, the girl singers are better than the boys, but everyone sharpens up as they go along. So you can probably miss the early rounds, if you want to watch the tennis. But the real winner will be Keith Urban, whose depth and texture will surprise and warm America the way it did everyone who saw The Voice. Plus sitting next to those divas, anyone’s going to look good.
