Nashville has descended on Dallas as country music's biggest stars are gearing up for the 50th Annual Academy of Country Music Awards.

And trust us when we say, the ACMs are truly pulling out all the stops for this milestone event.

Blake Shelton and Luke Bryan are on tap to co-host once again, with legends like Garth Brooks, Reba McEntire, George Strait, Brooks & Dunn, Martina McBride, and many (many!) more set to take the stage.

ETonline had eyes and ears inside AT&T Stadium in Arlington, Texas, on Friday, as McBride, Miranda Lambert, Brad Paisley and Lady Antebellum took the stage for rehearsals, and we're bringing you a sneak peek at their sets in the video above.

Lucky us: we are in for a two-song performance from Lambert, who, as the most-awarded female artist in ACM history, will accept her 50th Anniversary Milestone Award at the same time. Lambert's not only bringing her "Little Red Wagon" (with Gwen Sebastian in tow) to the stage, but she'll also sing the fan-favorite breakup anthem, "Mama's Broken Heart."

McBride, meanwhile, will provide a sure-to-be-memorable moment with a live rendition of her 1994 hit "Independence Day."

"It's the 50th anniversary of the show, so they're having some throwback moments," McBride told ETonline backstage. "I'm in a stage that's out in the middle of the audience, which will be a lot of fun to be surrounded by that many people."

Paisley will be "Crushin' It" with his performance, bringing a few familiar faces to the stage with him. While most artists are backed by simple graphics on a series of screens, Paisley is showing off a super-fun video in which he -- and, if you watch closely, Carrie Underwood -- put the lyrics into action, if you will.

And after a terrifying fire struck Hillary Scott's tour bus, Lady Antebellum is ready to bring the heat to the stage with their latest single, "Long Stretch of Love."

"It's gonna be a high energy performance," Charles Kelley tells ETonline. "It's very representative of where we are as a band and where we want to go, for a long stretch, and it's got a lot of high energy for us going into our tour starting here in May. The fans seem to be digging it."

The ACMs air live on CBS on Sunday, April 19th, at 8 p.m. ET/PT. Stay tuned to ETonline through the weekend for even more exclusive news, interviews, and red carpet glam.
