Gwen Stefani could be forced to cancel her Malaysian show after a Muslim group branded her “indecent” and “obscene”.

The singer, who is currently on the road with her ‘Sweet Escape‘ tour, is due to perform in Kuala Lumpur next month but the National Union of Malaysian Muslim Students want the concert scrapped because Gwen’s image offends Islamic beliefs.

Mohamad Hilmi Ramli said: “Her video clips promoting the event are too obscene. We want the organizers to cancel the concert, failing which we will ask the authorities to intervene.”

Ramli also slammed Malaysian mobile phone company Maxis Communications for promoting Gwen’s concert and exposing young Malaysians to “moral decay”.

He fumed: “Maxis has been staging a series of foreign acts to make a profit and to expose our young generation to things such as moral decay.”

Gwen’s Kuala Lumpur show is due to take place at the Stadium Putra on August 21.

The ‘Hollaback Girl’ singer will also perform in Australia, Japan, Singapore, Thailand, China and Hawaii before taking her tour to Europe.

Malaysia should pull the plug on the Kuala Lumpur leg of U.S. singer Gwen Stefani’s upcoming Asian tour because of her indecent dressing and obscenity, a Muslim students’ group said on Tuesday.

The 10,000-strong National Union of Malaysian Muslim Students said Stefani’s August 21 concert, which is part of her ‘Sweet Escape’ tour, would clash with local Asian and Islamic values.

Ethnic Malays, who are by definition Muslims, make up just over half of Malaysia’s 26 million people. Ethnic Chinese and Indians, who are mostly Buddhists, Christians or Hindus, form sizeable minorities.

Hilmi also criticized Malaysian mobile phone firm Maxis Communications for promoting the concert.

Maxis officials could not be immediately reached for comment.
