Clarkson and Brandon Blackstock were engaged late last year after knowing one another for quite some time. "We met years ago when I was working with Rascal Flatts, and he used to tour manage with him," Clarkson shared. "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.' 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."

This is the first marriage for Clarkson. Blackstock, 36, has two kids, Savannah, 12, and Seth, 6, from a previous relationship.
