BREAKING NEWS: Jay Z Storms Out On Beyonce!

Jay Z had 99 problems but Beyonce is no longer one! RadarOnline.com has exclusively learned that – as the 34-year-old "Single Ladies" superstar prepares for her world tour – her rapper husband has left their shared home for some time alone.

According to an insider, "Jay Z recently told his entire staff that he will not be needing them for another month!"

"He said that he has to take care of business and has a lot of traveling to do," the source continued.

"As Beyonce prepares for her upcoming tour, Jay Z said that he is going to use the time to take care of his own business."

Indeed, Jay Z has been spotted out and about in NYC several times since late last month, while Beyonce has been holed up in hush-hush tour rehearsals at GMT Studios in Culver City, Calif.

As RadarOnline.com previously reported, the 46-year-old rap mogul – who is also father to Queen B's four-year-old daughter, Blue Ivy – has taken a back seat to his wife's career in recent months.

Recent weeks have seen several big announcements about Beyonce's new fashion line, Ivy Park, and growing Record Label, Parkwood Entertainment, while Jay Z's career has been more quiet!

"Jay Z has been sweating the fact that his wife is trying to start her own empire right now and he is going into overdrive with making sure that it does not trump his own," a source previously told RadarOnline.com.

On top of that, as RadarOnline.com was the first to report, Jay Z's been involved in a nasty paternity battle with 22-year-old Rymir Satterthwaite, who alleges that the rapper is his father from an affair that he had prior to his rise to fame.
