The Since You've Been Gone singer's wedding was scheduled for the end of October, and even included Blake Shelton as officiant. However, the wedding coupled with the release of her Christmas album proved too much for Clarkson.
"We are so busy that we finally just came to terms the other night and were like, 'So, we change our minds and we want to elope," she told People magazine. "We just got so overwhelmed by it -- all the decisions."
Clarkson informed guests of her decision to cancel the wedding with an engagement photo and this message: 'Thank you so much for understanding, but it's just going to be me and Brandon and his two kids and the minister.'
