The star has previously laid her feelings bare in tracks such as Stronger, Since U Been Gone and The Trouble with Love Is, but now she's dating Brandon Blackstock she's finding it hard to focus.
She tells People.com, "It is killing me. I'm trying to write a tough song and it is coming out like butterflies and rainbows.
"People are going to be, like, 'What the hell happened to you?' It has been really difficult. I love it. It's an awesome problem to have."
Opening up about the romance, Clarkson adds, "People used to ask, 'Why are you single?' and I'd say, 'It is not in my schedule'. I'm in a relationship right now and I have time for it. I never used to."
