Cole, who's already worked with Cowell on the U.K. version of the singing competition show, is a multiplatinum-selling solo artist and a member of the female vocal group Girls Aloud.

"I just can't decide whether I am more excited to find and nurture the talent or for the unbelievable amount of amusement and entertainment I will have watching Simon doing everything and anything he can to beat me. He's tried to beat me for three years in the U.K., and hasn't even come close. His ego must be so bruised. America is gonna love this," Cole said.
