The CMA Awards will be crossing genres in 2014. Pop stars Megahn Trainor and Ariana Grande are booked to join Miranda Lambert and Little Big Town during their respective performances.

Trainor became somewhat of an overnight success with her hit 'All About That Bass,' an uplifting tune that encourages women (and men!) to love their bodies, no matter what size they are. That she and Lambert will perform the viral hit together is fitting, as Lambert has expressed many times that she's comfortable in her skin and is what she considers a normal girl.

“If you’ve got a little muffin top, that doesn’t define you,” the country star expressed in early 2014, speaking to women of the world. “You have so much more to offer: brains, talent, heart. You can spray-tan and suck in the rest. There’s Spanx for that!"

Trainor has a songwriting deal with Big Yellow Dog Music and has even penned a song for Rascal Flatts, so her duet with Lambert isn't too much of a stretch. It's not clear which song Little Big Town will perform with Grande. The pop princess' song 'Problem' has been climbing the charts as of late, putting her name in the spotlight.

The 2014 CMA Awards will once again be hosted by Carrie Underwood and Brad Paisley. Country Music's Biggest Night airs live from Nashville on Nov. 5 starting at 8PM ET on ABC.
