Brad Paisley and Carrie UnderwoodWhen the 43rd Annual CMA Awards show kicks off Wednesday night (Nov. 11), Carrie Underwood and Brad Paisley will take the stage as co-hosts for the second year in a row .

So how does this year compare to last year for Carrie?

"I think there's much more excitement this year as opposed to nerves last year," Carrie tells CMT Country Countdown USA host Lon Helton. Neither one of us had ever done anything like this before, and you just don't want to mess up. It's such a special night for everybody involved that you don't want to be the reason it's not as wonderful as it could be."

But what about Brad's randy reputation as a perennial prankster?

"I think I've got him under control," Carrie says with a laugh. "Yeah, I talked to Kim [Brad's wife, actress Kimberly Williams-Paisley]. Brad knows. He's a fun guy, he's a jokester, but he knows the limits. We can't be hiding Carrie's dresses on the CMAs. That's a bad idea. I'm just going to say that now. But I'm not worried. He's funny, he's a prankster, but he's also really professional so we both want the night to be an amazing night for everyone.

In addition to his hosting duties, Brad stands to be the night's big winner, with seven nominations. He's definitely got Carrie's support there as well.

"He deserves every single one," says the Female Vocalist nominee. "He's super talented and deserves every single drop of praise that he gets."

At least that what she says until one of her awards-show gowns goes missing!
