Blake Shelton to Officiate Kelly Clarkson's Wedding

Blake Shelton not only played cupid to Kelly Clarkson and fiance Brandon Blackstock, he will also serve as the master of ceremonies when the couple says I do.

Blackstock, a music manager who counts Shelton among his clients, proposed to the American Idol alum in December and has enlisted Sheltons help in more ways than one.

Hes not only singing, hes marrying us, Clarkson told Entertainment Tonight at Sundays Academy of Country Music Awards, referring to the country singer as Reverend Blake. He totally is, hes done it before with people.

In fact, Shelton will also officiate the forthcoming nuptials of wife Miranda Lamberts Pistol Annies cohort, Ashley Monroe.

Cla! rkson kept mum on the date of her own wedding, confessing that she has chosen a month to get married but the date is constantly changing due to conflicting schedules. She has crossed one item off her to-do list: picking the perfect dress.

I picked that out quick. Im not really that girl, she said.

When news broke of the couples engagement, Shelton told Hollyscoop that he had urged his pal to propose to Clarkson. I told Brandon, Man, you need to grow up and figure out that you need to marry this girl. I am going to go on record saying, 'I will do the music at the wedding or whatever you want to do, Ill 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, he continued.

Also likely to be in attendance at the celebration: Reba McEntire, who is married to Blackstock's father, Narvel Blackstock, who happens to be Clarkson's manager.

Clarkson and Blackstock have been dating since 2011.

A rep for Shelton did not immediately return The Hollywood Reporters request for comment.
