JAY Z BEEFING WITH FAT JOE?

I doubt it very much. Looks like someone is looking to stir up a bit of controversy by taking a verse from an old freestyle of Jay’s, adding a couple of verses from Uncle Murda to make it sound current and then debuting the track on thisis50.com as well as Kay Slay’s Fabricated Drama Hour (yawn yawn).
The verse which throws shots at Joe and DJ ‘We the Best’ Khaled, who Jay was kicking it with in MIA only the other day, is as follows:
“Gangsta, Gangsta, how you wanna do this? I clap n—as down for yappin’ all foolish, ain’t no stopping this Roc-a-fella movement. The name is Jay Guevera, homie, who are you? and, if your off-beat DJ, anything he play sound familiar? I’ll wait ’til Pharell say, “Play ‘em.’

Now I’mma have to diss you, Joe. You can get a smack for that, matter fact, the gats will blow….your toy squad will get squashed, Boy–yard dee, you’re lost in the sauce partly because your boss ain’t a leader. He’s a follower. No, I’m not coppin’ ya album or your single, most likely you’ll go copper…”
Any guesses as to who would be cooking up imaginary beef like this?
