London, July 26 (IANS) Pop superstar Madonna is reportedly trying to save her marriage to British director Guy Ritchie by inviting all her friends for a 'Shabbat Nachamu' - a night of consolation according to Jewish custom.

The ceremony will be supervised by two rabbis on the weekend of Madonna's 50th birthday that falls Aug 16. A few close friends will be present as the couple try to reassure everyone that their marriage is still on, thesun.co.uk reports.

A close friend said: 'They have a special Shabbat party in August - separate from Madonna's 50th (birthday). It's Shabbat Nachamu - which they want to do once a year to declare their feelings for each other. It's a very important dinner for them - they want everyone to know they are still in love.

'She and Guy are making speeches in front of the rabbis. Knowing Guy, he'll have a laugh with it and they'll make light of the whole thing. But there is a serious message.'

The friend added that the children - Lourdes and Rocco - are important for the couple.

'The kids mean the world to them both and they are determined they will stay together.

'Family members have been suggesting to them they get counselling. Em (Madonna) wanted to do something more biblical and spiritual. There are other reasons for the dinner. Guy's dad John's health is failing. It's why Guy wants to stay in the UK.'
