Keith Urban struggles with `American Idol` conflicts

London: Country star Keith Urban is having a tough time on `American Idol`, because he is upset about Mariah Carey and Nicki Minaj`s feud.

The 44-year-old and another judge Randy Jackson were caught in the middle when Carey and Minaj had a furious bust up earlier this week, leading to auditions being cancelled for a day, reported a website. "Keith is such a wonderful, easygoing, lovely guy. This kind of drama was not the reason he signed on to be an Idol judge. He hates nastiness in any form," a source said. PTI
