In a copy of the Save the Date invitation obtained by Radar, the note reads:
"Bookmark the date for the wedding of Kelly and Brandon," including the date and location saying, "Formal invitation to follow."
Kelly has been vocal about her relationship with Brandon telling Ryan Seacrest in an interview that it was love at first sight.
"We met years ago when I was working with Rascal Flatts, and he used to tour manage with him. I didn't really know he was my manager's son and it was kind of weird. I was like, 'Dude, I gotta know that guy,'" Kelly said.
"We were just in a room together, and then he came up and said he was from the same hometown as me and I was like, 'Oh we're so getting married,' I was so that girl. When he became single, I was on the prowl."
