The concert which made by haifa wehbe & ragheb alame in stilla hayde didnt attened more than 600 person as some sources wrote , some refer that to amro diab concert .
i dont know do you think that.
amro diab is a star but i dont think he will cover the big success of ragheb & haifa maybe there is another reason , because also there is many many people love those 2 stars.
