Kelly Clarkson saying "I do" to Brandon Blackstock is pretty much going to be the country music equivalent of the royal wedding.

Not only is the "Don't Rush" singer marrying Reba McEntire's stepson, but Blake Shelton is officiating their wedding!

When Entertainment Tonight's Nancy O'Dell asked Kelly, 30, if the Voice coach was performing at her upcoming nuptials, she gushed, "He's not only singing! He's marrying us.  He totally is…He can be very sentimental."

"He's done it before with people. He's actually marrying Ashley Monroe from the Pistol Annies as well," Kelly said, quipping, "Well, you're technically already married when the ceremony happens. So it's not like it's gonna be null and void or anything 'cause it's Blake."

As for when Kelly's special day will happen? It's still kinda TBD. "We honestly don't have [our wedding date set] quite yet!" she said. "We have the month, but we don't have the date."

Kelly does already have her dress picked out for the big day, but there were no bridezilla moments involved in finding it. "I picked that out quick," she said. "I'm not really that girl. I picked everything out super quick…I could like totally show up at the Justice of the Peace and be like, 'This is fine!' But, my mom would kill me."

Take note, boys: Low-maintenance girls are marriage material.
