Cairo - RnB singer Beyoncé, who put off a gig in Malaysia following Islamist outrage over her "gyrating moves" and "sexy outfits", has brought her world tour to Egypt and more hostility.
Hamdi Hassan, a lawmaker from the Muslim Brotherhood, has written to the speaker of the house and the interior minister labelling her planned show on Friday night a "sex party" and demanding to know why she was allowed to perform.
He said the concert advertisement, in which the comely diva wears a leotard fitted with motorbike handlebars extending from her crotch and a headlight nestled in her cleavage, "threatens social peace and security".
"I do not know who agreed to this sinful, unacceptable advertisement, or indeed who agreed to these blatant sex parties," Hassan wrote, accusing the government of encouraging "sin and debauchery".
Meanwhile, a group on social networking site Facebook opposing her concert has attracted nearly 10 000 members.
One poster displayed on the site, showing the silhouette of a curvaceous woman with a diagonal red line through it, was entitled "This is not Egypt".
Beyoncé, who once told an interviewer that she "likes to dress sexy", has so far drawn about $50m on her I Am... world tour, and there's no word yet on what she will be wearing.
In October, Beyoncé postponed a concert outside Kuala Lumpur after an official of the Pan-Malaysian Islamic party expressed sharp disapproval.
"We are not against entertainment, but it's the way she performs - her gyrating moves on stage and her sexy outfits. It will erode the moral values of our young people," said PAS youth chief Nasruddin Hassan Tantawi.
Marctensia, organiser of the Malaysian concert, had said Beyoncé would tone down her attire.
It insisted the postponement was "solely the decision of the artiste and has nothing to do with other external reasons" and that a new date would be announced.
In Egypt, the concert is still set to go ahead, under tight security, at the Red Sea resort of Port Ghalib.
Racy music videos
The best tickets are going for 2 000 Egyptian pounds ($366), well above the means of most Egyptians.
The banned party Muslim Brotherhood is effectively Egypt's main opposition party and is widely popular for its social work. It runs candidates as independents in parliamentary elections to get around the ban.
The party, which calls for the establishment of an Islamic state by peaceful means, normally focuses its flak on government corruption and foreign policy, but has campaigned against what it considers prurient literature and art.
Most Egyptian Muslim women wear head scarves in accordance with Islamic custom, and the poverty-ridden country has lurched toward religious conservativism.
But the country is arguably the capital of the Arab world's film and music industries, and satellite channels with Arab pop stars in sometimes racy music videos have a wide audience.
And Western singers regularly perform in Egypt. In February, pop singer Akon, famous for his hit single Smack That, peeled off his shirt and dove into the crowd.
It is still to be seen what sexy outfits and gyrating moves Beyoncé offers the crowds on Friday night. But long after she is gone, nightclubs will still have plenty of both on offer - as belly dancers delight both Egyptian and foreign audiences.
