Mariah and Nicki will sort out their differences: Barack Obama

Los Angeles: Mariah Carey and Nicki Minaj`s fued on `American Idol` has even reached President Barack Obama, who hopes that the two artistes will sort out their differences.

Obama, 51, called in to Michael Yo`s radio program `The Yo Show` and was immediately asked about the ongoing fight between the new reality show judges, reported Ace Showbiz.

"I think that they are going to be able to sort it out, I am confident. I`m all about bringing people together, working for the same cause. I think both outstanding artists are going to be able to make sure that they`re moving forward and not going backwards," Obama said.

Asked about his own personal favourite between the two artistes, President said, "Mariah, she`s actually done some events for us. I`ve gotten to know her and Nick (Cannon), she`s a wonderful lady. Nicki I don`t know, but I`ve got her on my iPod."
