Jay-Z is already working on a blockbuster comeback world tour for Beyoncé after the birth of their daughter, Blue Ivy. Sources tell us Jay has approached Live Nation about a $150million deal for Beyoncé to tour following the birth of their child in January. Beyoncé has a joint management deal with Jay’s Roc Nation and Live Nation. A source told us, “Just weeks after the birth of Blue Ivy, Jay met with Live Nation to discuss a tour for Beyoncé. He wanted a deal worth about $150million, but they countered with a lower offer.” Beyoncé had earlier hinted that she may tour again this year. Reps for Jay-Z and Beyoncé didn’t get back to us. Live Nation reps declined to comment.
