Usher and Shakira Talk Failure of ‘American Idol,’ ‘The Voice’ on ‘Next Chapter’

Are Usher and Shakira responsible for the success of "The Voice," this season? Did they help to pull viewers away from "American Idol"?

Oprah poses that question on Sunday's airing of "Oprah's Next Chapter," featuring the cast of "The Voice."

"I do feel there is a special chemistry between us four," Shakira offered in response to Oprah's question, noting that "The Voice" actually topped "American Idol" earlier this year.

Opting out of answering, Usher allowed Shakira to go further.

"I don't know. We just have fun and I think that translates…. and it's very genuine, whatever is happening," said Shakira. "Whatever you see on TV is exactly what's happening."

"Oprah's Next Chapter," featuring the cast of "The Voice," airs tonight (Sunday) at 9 p.m. on OWN.
