Carrie Underwood's choice to perform at the inauguration might make for a tense 'American Idol' season with fellow judge Lionel Richie. Here's what a source shared.

Four Arizonans will compete on "American Idol" Season 23. It premieres on March 9 with Ryan Seacrest, Carrie Underwood, Luke Bryan and Lionel Richie.

As previously announced, Emmy® Award-winning television host, writer, producer and comedian Conan O'Brien will host "The Oscars," which will air live coast to coast SUNDAY, MARCH 2 (7:00-10:30 p.m. EST/4:00-7:30 p.m. PST), on ABC. The telecast will also be rebroadcast in the Pacific Time zone in primetime after the live presentation.

“I’ve got mine that if you start singing it, I'll start having shakes and hives and I'm close to passing out,” Lionel Richie tells Entertainment Weekly. “It didn't happen this time — ‘ It's a Man's World ,’ which I've heard for seven years. When they start singing ‘It's a Man's World,’ I go, ‘Don't do it. It's not gonna work.’”
