(Rumor) Celeb snoops at The Rumor Mill are dishing that Jay-Z plans to ditch Def Jam later this year to create a new “super label” with his main chick Beyonce.

A supposed insider claims that the new label will launch early next year:

“It’s a done deal. [Jay Z] already has Beyonce and [Mathew Knowles] on board … She’ll be finishing up her contract [with Sony], and I expect that she’ll sign on to the new label shortly afterwards.”

“Jay Z brought the idea to Def Jam first, but they thought he was asking for too much money.” The insider continues, “Now they’re shopping the deal around to the other majors and to Apple [the creator of iTunes] - who is very interested in doing business.”

And if there’s any truth to this “Super Label” scoop, several of Def Jam’s major acts will also be jumping ship:

“Jay Z has a clause in his [Def Jam] contract that says he can buy the rights to any artist he’s signed - that would include Rihanna, Ne-Yo, and Nas.”

“People here are shaking in their boots over this rumor … What do you think would happen to this company if Jay Z left and took Ne-Yo and Rihanna with him.”
