The rapper is desperate to save his marriage and plans to whisk his superstar wife away on a five-week "make or break" vacation in between their final tour dates.

According to a source, Jay Z is trying to persuade Beyonce to join him.

"Jay wants to save the marriage, they have their final US tour date in San Francisco on August 6 and then they have two dates in Paris from September 12 - that's it.

"He adores his daughter Blue Ivy and he wants a sibling for her, but Beyonce isn't sure what she wants to do. Their marriage is in flux, that's the truth. Jay just wants them to spend some time alone together to try and work it out," said the source.
