Superstar couple Beyonce Knowles and Jay Z's marriage is reportedly in trouble and are said to be staying in different hotels on tour.

They are reportedly sleeping in separate hotels while on their "On The Run" world tour as their marriage is reportedly on its last legs, reports contactmusic.com.

The couple, who got married in 2008, have been plagued by rumours of cheating.

"They're not just staying in different hotel rooms, but they have booked separate hotels, and they arrive separately to each show," a source explained.

They are managing to play the loving couple while on stage and are said to be taking part in online counselling sessions via video chats.
