'Separate lives' for Beyoncé and Jay Z

Los Angeles - Beyoncé and Jay Z will ''lead separate lives'' on tour.

The couple - whose marriage has been the subject of speculation it is in crisis - kicked off their joint On the Run concert series last week, but they are said to be only seeing one another on stage, as they travel separately and stay in different hotel rooms.

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

''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.''

The couple - who have two-year-old daughter Blue Ivy together - have both been the subject of rumours of infidelity and the insider admits they are struggling to trust one another.

The source told Grazia magazine: ''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.

Jay's given Beyoncé unlimited access to his texts and e-mails to try and keep the peace, but a lot of their communication will be through assistants.''

Despite the claims, the pair have seemed comfortable on stage with one another and even treated fans to previously-unseen footage from their wedding.
