The red-hot singer and her boyfriend, Gym Class Heroes' Travis McCoy, have reportedly ended their year-long relationship.

"It's sad, but they were fighting a lot because they never saw each other and now she is going on tour," an insider told UsMagazine.com. "She just needed a clear head. It's been non-stop work for her."

Travis went down the broken-hearted teenager road and posted on his blog the lyrics to some song about the breakup.

"We fight every night, now that's not kosher. I reminisce with bliss of when we was closer. And wake up to be greeted by an argument again, You act like you're 10...My friends always tell me how I'm lucky to possess the best looking girl in the whole U.S....it seems like just two years back when we were bonded and not pierced, but now I keep itchin' to jet," he wrote.

Kinda silly, but a broken heart can lead one to do many, many silly things. I could teach that class.
