A SNOWBALL’S CHANCE IN SOUTH FLORIDA: The Internet is buzzing with a report that Jay-Z, who peeled $1 million to become a minority owner of the New Jersey Nets, feels dissed by his friend LeBron James because the hoops star kept the hip-hop star out of the loop on his decision to join the Miami Heat. Mediatakeout.com quotes an "EXTREMELY CREDIBLE insider" saying LeBron "Jay-Z felt disrespected that King James did not consult with him during the free agency process," or even take his calls. N.Y. Daily News gossip column Gatecrasher got a similar take from a source in Hova's camp. "Jay never expected LeBron to sign with the Nets. He knew that no 25-year-old kid with James' profile was going to spend years in Newark. But he's pissed, or at least disappointed, that LeBron didn't consult with him. [But] I don't think it's going to affect their friendship." (7/28a)
