Talk about your Best Week Ever. As buzz builds that Jay-Z and Beyoncé might trade vows as early as Friday evening, the biz's biggest name in hip-hop has inked a mammoth $150 deal with, no, not longtime home Def Jam, nor a rival label, but concert promoter Live Nation (which threw similar big bucks at Madonna a short while back). The pact demonstrates "how significantly the music industry has shifted," Blender editor-in-chief Joe Levy tells the New York Daily News. "The greatest rapper in the world doesn't want a record label anymore."

The terms of the deal are said to award 38-year-old Jay-Z (aka Shawn Carter) $25 mil upfront, another $25 mil in advances, and then $10 mil each for at least three albums. He also gets $50 mil in seed money for his entertainment company.

As for his romantic success, the News hears that friends of Jay-Z and Beyoncé have been invited to the rapper's Manhattan digs tonight, though officially the duo's reps have held firm with a "no comment" on this week's marriage talk.
