Fox is showing how different the atmosphere will be at the judges' table on "American Idol" this season. The first peek at the new season shows Harry Connick Junior cracking up Jennifer Lopez and Keith Urban and all judges seemingly getting along, unlike last season when Mariah Carey was feuding with Nikki Minaj. The preview showed two singers from Detroit being praised by the judges. Keith Urban says one of them looked like a lost Osmond brother, Ronny Osmond. The other is an R-and-B singer who Connick says will be "a nightmare" to the other contestants because she's so good. Of course, they had to show some clunkers, too, including a mumbler and a guy who twerked to "Somewhere Over the Rainbow." Season 13 starts January 15.
