'Catch My Breath' hitmaker Kelly Clarkson has opened up about her forthcoming wedding plans and revealed that she will have a well-known singer perform at the ceremony.

Speaking to radio station K-Frog, Clarkson, who is engaged to Brandon Blackstock, explained that they have asked country star Blake Shelton to play at their reception:

"Blake actually is going to play at our reception, so we're pretty excited."

She added that the actual ceremony might take place outside later this year as the weather would be perfect:

"We're just kind of overwhelmed with the planning of the wedding. We're actually thinking the fall this year. We're thinking outside. We are trying to make it small, but it is hard. Once you've got one person, you have to invite five others, and then five others... I literally had a breakdown two weeks ago about the wedding list."

"I'm actually terrified at everyone watching me walk down an aisle, that is like the worst thing ever."
