Although Kelly Clarkson’s performance was flawless at the ACM Awards on Sunday night (April 7), that’s not what made headlines backstage at the MGM Grand.

Kelly surprised Entertainment Tonight’s Nancy O’Dell by confirming that Blake Shelton will not only sing at her and Brandon Blackstock’s wedding -- he will also officiate the ceremony.

What?  That’s right, Blake will marry Kelly and Brandon in October! Blake is making officiating weddings a regular thing. He will also officiate Ashley Monroe of the Pistol Annies' wedding as well.
