Seemingly their two-year relationship has hit the skids "after weeks of arguments over her busy 2009 touring schedule" (AKA since she's become way more famous than him). A rep for Perry said: "It's a hardship, but she's regrouping", while Travis McCoy of the Gym Class Gimps chose to post the following rap(??) on his blog:

"My friends always tell me how I'm lucky to possess
The best looking girl in the whole U.S.
But every time you scream, you blow your finesse
Tryin' to dis the Profess-
Or twenty-four hours of acting sore
Sometimes I wish you'd come down with lockjaw
So I don't have to take in the breakin'
You treat me like a burnt piece of bacon
It seems like just two years
Back when we were bonded and not pierced
But now I keep itchin' to jet
Sitting in the chair just to stare, set to sprint
Yo, sweetheart, you better take a hint
I say it now like I said it before
I'm lookin' at the front door
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"

That some profound sh*t right there. And it's OK *ahems* 'Profess'... you are not alone. I too wish she'd come down with a thorough bout of lockjaw.
