Not so crazy in love? Beyonce and Jay Z may look cozy on stage, but in private, the two have continued to spend time apart amidst reports that their marriage is in trouble, multiple sources reveal in the new issue of Us Weekly.

"They stayed separately in both New York and L.A. for several nights," an insider close to the rapper, 44, tells Us of how Jay and Bey have been avoiding each other during their joint On the Run tour. 

Even more telling, a real-estate insider says the "Single Ladies" songstress, 32, has been touring apartments solo in NYC's Chelsea neighborhood. "There was no Jay Z in sight," the source tells Us.

Despite continuing to show their love on stage—the parents to Blue Ivy shared a kiss on Aug. 3 during their show at L.A.'s Rose Bowl—sources predict the duo will announce they're splitting after the tour wraps Sept. 13. 

However, another source close to the couple—who married in 2008—is adamant that "they are happy."

"They have issues, like every other couple," the Beyonce pal insists.
