The final three in the series finale are set on FOX's American Idol.

FOX's Michelle Pollino reports:

It's now down to the final three on FOX's American Idol: Trent Harmon, of Amory, Mississippi; Dalton Rapattoni of Dallas; and La'Porsha Renae of McComb, Mississippi.

One of them will be crowned the final American Idol next week as the series ends after 15 seasons...

Mackenzie Bourg of Lafayette, Louisiana, was eliminated after receiving the lowest number of viewer votes among the final four.

The two-part finale, airing Wednesday and Thursday, will feature performances by past winners including Kelly Clarkson and Carrie Underwood and other surprise appearances.
