Blake Shelton is marrying Kelly Clarkson. No, he’s not splitting from Miranda Lambert, he’s officiating at Clarkson’s wedding to fiancé Brandon Blackstock!

And here we all were thinking he was just going to sing. Kelly revealed the news to Entertainment Tonight at Sunday’s ACM Awards, adding that Blake will also perform at the festivities.

Blake has taken credit for getting Brandon to pop the question. "I told Brandon, man, you need to grow up and figure out that you need to marry this girl," Blake told Hollyscoop this past December. "I am going on the record saying, I will do the music at the wedding or whatever you want to do, I'll be that guy. I will play for four hours if I have to, cause you need to get your head out of your ass and ask that girl to marry you."

Here's Kelly explaining to ET that Blake is going to marry her:
