Kelly Clarkson's romance is like a cheesy love song

Kelly Clarkson has gushed about her boyfriend Brandon Blackstock, comparing their romance to a "cheesy love song".

The Since U Been Gone hitmaker was single for most of her time in the spotlight until hooking up with Blackstock, who is her manager's son, last year after a lengthy friendship.

And Kelly Clarkson admits she's so loved up their relationship could be the basis for a sickly ballad.

She tells the Associated Press, "I completely fell in love. Welcome to Cheeseville! I did. I don't know. Your priorities kind of shift and you become happier and all that stuff.

"It's probably my best accomplishment because I think, for me, especially, I just didn't think it would happen. It's like one of those cheesy love songs that didn't exist, but it does, so that's cool."
