Ever since the video of Beyoncé's sister Solange attacking Jay Z in a lift after the Met Gala leaked online, rumours are abuzz saying the music power couple's marriage is on the rocks.

There are reports that Queen Bey and Jay Z are advised to keep mum about their relationship status until their nationally sold-out tour On the Run comes to an end, New York Daily News reported.

The Single Ladies singer is reportedly shopping for a luxury apartment, where she will move with her two-year-old daughter Blue Ivy post her divorce.

The hip-hop power couple is reportedly advised to play the 'happy family' before the media and paparazzi until their popular tour wraps up this September.

"Let's leave it at it's only a matter of time (until they split.) It's so obvious now it's embarrassing," a close source to Bay and Jay told the website. "Around the time the tour ends, they'll make a choice on whether they want to separate or admit trouble," the insider added.

The website also reported that now the couple is together due to business but will issue a joint statement after the end of their tour.

"This (trouble) has been brewing longer than anyone knows," the close source added.

"They're performers. And they're good performers. It's a business now, and they are business partners. And they don't even fight. They know what it is," the source added.

The website also reported that the Halo singer and her 44-year-old rapper husband are desperate to end the rumours and are advised to post a family picture with Blue Ivy.

Amidst the marriage breakup rumours, the singer has posted a loving picture of her daughter and husband on Instagram with the caption "My favourite hue is Jay Z Blue".

"He wants this tour to end and he wants the rumours to stop," the website quoted another source.

"They are both being advised on how to look like they're together. A negative report comes out, or a breakup report comes out, and they are advised to post a picture with Blue Ivy," the source added.
