Brad Paisley + Carrie Underwood Travel Back in Time in Hilarious CMA Awards Commercial

We're only a few weeks away from the 2014 CMA Awards, and Brad Paisley and Carrrie Underwood are gearing up for even more jokes -- including some at their expense. The singers, who are returning for the seventh year as co-hosts of the ceremony, reminisce in a new commercial about when they first started emceeing the event.

“Can you believe this is our seventh year hosting the CMA Awards?” Underwood asks.

"Remember how it all started?" Paisley questions, before two children portraying a younger Paisley and Underwood appear, along with school pictures of several of today's biggest stars, including Luke Bryan, Miranda Lambert, Lady Antebellum, Tim McGraw, Jason Aldean, Dierks Bentley, Keith Urban and Blake Shelton.

After explaining that Shelton couldn't be there in person because he was grounded, they return to their adult bodies, but learn that Shelton still won't be able to be at the upcoming CMA Awards because, according to Paisley, he's "grounded again," prompting Underwood to exclaim, "Miranda!" in exasperation, shaking her head.

The two longtime friends are accustomed to poking fun at each other, but it sounds like this year, the pregnant songstress might take the brunt of the jokes.

“I mean, who knows? Did you guys see her at the ACM Honors?” Paisley says. “She was a basket case. So what’s she going to be like in the monologue when we do this? Is she gonna break down crying? Or is she all of a sudden gonna start laughing for no reason, have a hot flash? Run off stage and pee. I don’t know.”

The 2014 CMA Awards will air live from Nashville's Bridgestone Arena at 8 PM ET on ABC.
