American pop stars Lady Gaga and Ariana Grande are on an “offensive lyrics” list presented to members of parliament in socially-conservative Singapore as part of a statement by the city-state’s home minister on hate speech.

Monday’s statement came nearly a month after Swedish black metal group Watain’s concert was banned in Singapore on concerns about its history of “denigrating religions and promoting violence”.

Singapore keeps a tight rein on public speech and the media, especially when it comes to race and religion.

A photo of the ministerial statement on “restricting hate speech” was posted on Facebook by opposition MP Chen Show Mao on Monday with the caption “lesson of the day”.

The post had been shared more than 1000 times and received hundreds of comments by Tuesday afternoon.
