Beyonce is facing another backlash from Islamic groups - conservative Muslims in Egypt fear her upcoming concert will threaten the country's "social peace and stability."

The Crazy In Love superstar is due to take her I Am... world tour to the mostly Muslim nation on Friday. But strict Islamic groups have complained to the government for allowing the show to go ahead, branding it an "insolent sex party."

In a letter to authorities, a representative for opposition group Muslim Brotherhood writes, "Why are you encouraging this insolent sex party? You are accused of disturbing social peace and stability, encouraging vice and debauchery."

The criticism mirrors similar outrage in Malaysia last month, when Muslim leaders led protests against Beyonce's sexy on-stage antics. The star subsequently scrapped her concert in the capital, Kuala Lumpur.

However, the Egyptian event organizer has dismissed the criticisms - insisting not all Muslims are offended by Beyonce's performances.

Ahmed Beltagi says, "We are Muslims too... this will not stop Egypt from hosting an award-winning, first class artist. We should salute her instead of criticizing her."
