Lady Gaga was warned by an Islamic group that it would not let her set foot in Indonesia, challenging an army of fans awaiting a concert. The group also vowed to mobilise 30,000 demonstrators to protest the US artist’s June 3 performance in Jakarta and to intercept her at the airport. The group called her ‘dangerous’ and her style ‘vulgar’. The US pop diva, famed for her outrageous outfits and provocative performances, has sparked opposition in other Asian countries with her ‘Born This Way Ball’ global tour, which kicked off in Seoul last month amid protests. Some 40,000 fans plan to attend the sold-out show in Indonesia. Little Monsters-as Lady Gaga fans are called-tweeted their determination to see the pop idol perform in Indonesia. One page on Facebook, which is wildly popular in Indonesia, was seeking dancers for a Lady Gaga flashmob, which sees people perform a choreographed dance in a public place. The flashmob is “to show our appreciation to Lady Gaga for planning to visit and to tell others who don’t approve of her that there’s nothing wrong with being her fans,” said Anggiat Sihombing, an 18-year-old university student who set up the LadyGagaIndo account. “We like her because she is a famous musician who makes use of her popularity to do good deeds, like establishing a foundation to protect kids who have been bullied.” The Lady Gaga Indonesia Facebook page has more than 42,000 “likes”. Despite the opposition to her tour, the “Poker Face” singer has not toned down her performances-at the Seoul show on April 27 she rode onto the stage on horseback, wearing a black bodysuit and an enormous black metal headpiece.
