Us Weekly posted the pic of the happy couple out together for the first time in public.

Check it out HERE

Kelly and Brandon were at the Barn Party Bonfire Celebration in Tennessee.

So will Kelly’s new love ruin the tough “girl power” anthems that she’s known for? She told US Weekly:

“I’m too happy! He’s ruining my creativity!” she joked. “I’m writing all this happy sh–! It’s killing me.”

“People are going to be like, ‘What the hell happened to you?’ It’s difficult. But awesome!” she added. “I’m not complaining. It’s an awesome problem to have.”

LOL! As long as she’s happy… we’re happy to have whatever music she puts out!
