Kelly Clarkson Wedding: Blake Shelton Will Officiate The Ceremony (VIDEO)

We already knew that Blake Shelton will be singing at Kelly Clarkson's upcoming wedding -- now, it turns out he's also performing the ceremony!

Clarkson told Entertainment Tonight's Nancy O'Dell Sunday that Shelton will be officiating her wedding to Brandon Blackstock (who is Shelton's manager), and that he "loves" performing weddings.

"He's very serious. He's so into it. He can be very sentimental, and it's like, what? You don't know how to take it," Clarkson said.

Clarkson also revealed that it was easy to find her wedding dress.

"I'm not really that girl. I picked everything super quick," Clarkson said. "I could totally show up at the justice of the peace and be fine, but my mom would kill me."
