Singer Beyonce Knowles and rapper-husband Jay Z have reportedly been undertaking online marriage counselling sessions with a therapist.

The couple, currently on their joint On The Run world tour, is said to be taking counselling sessions on the internet via video-chat programme Skype, to keep their relationship going strong, reports contactmusic.com.

"It might sound drastic but in America especially, counselling is fairly standard procedure,` said a source.

"They have known their therapist for a long time and try to have weekly sessions just to keep communication open and make sure there are no misunderstandings,` the source added.

The two got married in 2008 and have a two-year-old daughter Blue Ivy.
