What do you get when you pair Kacey Musgraves, Lady Antebellum frontwoman Hillary Scott and Kelly Clarkson together? A flawlessly-executed performance, showcasing one of each woman's hits! That's what the ladies did Tuesday night (Sept. 9) at the 2014 ACM Honors, much to the delight of the star-studded audience.

Held at the Ryman Auditorium in Nashville, the trio of women performed at the event, which takes place each year to spotlight ACM's off-camera award recipients. Their performance was in honor of Shane McAnally, who was presented with the Songwriter of the Year award. Fittingly, they joined together on three of his hits, including Musgraves' 'Merry Go 'Round,' Lady A's 'Downtown' and Clarkson's 'Tie It Up.'

Each singer took her turn with the lead, with the other two providing backup vocals. The diverse collection of songs was met with lots of applause and cheers. Right before Musgraves took the lead, she said, "We love you Shane. Congrats!"

Other awards presented during the evening included special categories, industry awards and awards for musicians, producers and songwriters. Country stud Jake Owen hosted the show, telling the audience early on that the night "is all about putting down our phones and celebrating country music." In addition to hosting duties, Owen performed 'Back of My Mind Again' in honor of Ronnie Milsap -- recipient of the Career Achievement Award, along with Toby Keith.

Carrie Underwood was presented with the Gene Weed Special Achievement Award, giving a nod to her charity work, and the expectant mom broke down as she gave her gratitude to husband Mike Fisher and her team.

"I was getting misty-eyed sitting in the audience," Underwood said. "I had all kinds of stuff to say you guys and it's all gone. I am so honored and so thankful and so blessed."

After she left the stage, Owen was sure to let Underwood's husband, Mike Fisher, in on a little secret: pregnant women can be emotional at times.

Among several other specialty awards of the evening were country group Rascal Flatts and Steve Buchanan, executive producer of ABC's 'Nashville,' who were presented with the Jim Reeves International Award. Additional performers included Hunter Hayes, the Oak Ridge Boys, Lee Ann Womack and others.
