Beyonce Knowles, Jay Z going separate ways?

Los Angeles: Singer Beyonce Knowles and husband-rapper Jay Z will reportedly "lead separate lives" while touring.

The couple, whose marriage is said to be in trouble, recently began their joint `On the Run` concert series but they are said to be only seeing one another on stage, as they travel separately and stay in different hotel rooms, reports.

"They might be sharing a stage, but while on tour they`ll live practically separate lives," said a source.

"Tensions between them are worse than ever, meaning they will be travelling between venues independently, staying in different hotel suites and even having separate entourages....

"They`ll also have individual dressing rooms, so the only times they`ll be together will be while they`re performing," added the source.

The parents of two-year-old Blue Ivy have been the subject of rumours of infidelity.

"They`ve both been dreading the tour. Cancelling wasn`t an option, so on the surface it`s going to be business as usual, but they`re both struggling with trust issues after the spate of cheating allegations," said the source.
