The story was first broken by US magazine Star, who published it on their website before immediately taking it down. According to insiders, the superstar couple have agreed on a 'trial separation' while they attempt to sort out their differences.
The trouble reportedly began when rap mogul Jay chose to embark on his Magna Carta: World Tour without checking with his glamorous wife, who was under the assumption that he would be supporting her on her Australian tour leg.
Instead, Jay is said to have chosen his own European route, making no effort to co-ordinate dates with his superstar wife.
Beyoncé, Jay-Z and daughter Blue Ivy were recently spotted spending some quality family time together at a private resort in New Zealand. But according to insiders, the trip was less of a holiday and more of an opportunity for the megastar couple to save their marriage.
Star has now removed the story from its website - but the full details are expected to hit the front cover of the magazine on November 25.
In happier news, a source for HollywoodLife.com has since revealed about the rumours: 'Their marriage is fine, they’re working on getting together more for the holidays, and nobody should expect a breakup, separation or divorce.'
Citing that Beyonce and Jay-Z simply have 'normal relationship problems', it adds that Bey's lengthy Mrs Carter World Tour is just 'adding stress to a marriage that is not only important to them, but an entire fan base.'
We really hope that's true. Do you believe the rumours?
