Kelly Clarkson's divorce with Brandon Blackstock is totally drama free. Sources tell The Blast that there's no significant incident regarding their decision to split, as in no one cheated, and their divorce is completely "amicable." We're also told that the former couple's friends are completely blindsided by the divorce news. One source says it didn't appear the two were having any issues and they are shocked that Kelly Clarkson filed for divorce. As The Blast reported, the singer filed last week after six years of marriage.
