Beyonce?

Two members of AD.ca forums wrote that Amr Diab had recorded a due with the American hot singer Beyonce. The first member source is Kalam El-Nass Magazine, while the other said that he listened to the news from MBC-FM which called it "Exclusive." MBC-FM is really close to the production company Rotana and this could be true.
I hope this is true, as it's going to be the hottest news of this summer!
