Lady Antebellum is bringing their newest song 'Bartender' to the 'American Idol' stage.

It's not just any 'Idol' episode; it's actually the season finale, which will make Wednesday evening (May 21) even more exciting. A fan-favorite country trio plus a newly-crowned 'Idol' winner? We can hardly wait.

The two finalists (Jena Irene and Caleb Johnson) will hit the stage Tuesday to give America one more look at their talent, and then Wednesday will bring a slew of performances, FOX announces, including country stars Lady A, Jennifer Nettles, and Darius Rucker, as well as several other celebrity singers such as Demi Lovato, Jason Mraz, KISS, John Legend, and Aloe Blacc. Irene will duet with Paramore, Johnson with KISS, and Alex Preston (third finalist) with Mraz.

Lady A is working hard on their fifth studio album, and 'Bartender' is a rocking woman's anthem, with Hillary Scott fittingly taking the lead. It's not a typical song about heartbreak, which all female fans will appreciate.

Says the songstress, "As a female, I love the fact that it’s not this song about her (saying), ‘My hearts been broken, it’s so sad, he did me wrong.’ It’s not about going and rebounding with some other guy. She’s just going out with her friends and having a night to forget about what this dude just did to her. I love that as a woman, kind of taking the reins in a situation and getting over it in a fun way.”

Don't miss 'Bartender' on 'American Idol' this Wednesday, at 8PM ET on FOX. America's newest idol will be announced at the end of the show.
