CAIRO (AP):

As Egypt gears for pop diva Beyoncé Knowles' first performance in North Africa, Islamic conservatives are branding her show an "insolent sex party" that threatens the Muslim nation's "social peace and stability."

On giant posters plastered across the Egyptian capital advertising today's concert, Beyoncé sports a revealing, flame-covered outfit and grips a set of motorcycle handlebars extending from her hips - a sharp contrast to Cairo streets, where most women wear the traditional Muslim headscarves. TV ads promoting the show, part of Beyoncé's 'I Am ...' world tour, have run on Egyptian and Arab satellite stations.

Grossed US$53.5 million

The tour, which also took Beyoncé to the United Arab Emirates last week, had grossed US$53.5 million as of October, according to Billboard magazine.

But in Egypt, Islamic lawmakers and their supporters have waged campaigns on social networking websites, accusing the government of encouraging debauchery and calling for the concert's cancellation.

"Why are you encouraging this insolent sex party?" lawmaker Hamdi Hassan from the opposition Muslim Brotherhood wrote in a letter to the government. "You are accused of disturbing social peace and stability, encouraging vice and debauchery."

Another Islamic lawmaker, Ali Laban, called for banning the "nudity concert."

A Facebook campaign against Beyoncé's concert collected nearly 10,000 supporters.

But the war of words has not derailed the glitzy concert, due hundreds of miles south of Cairo in the luxury Red Sea resort of Port Ghalib. Organisers said "ultra" security will be deployed to protect the thousands of concertgoers.
