The Dominican Republic government commission that oversees public performances is banning a Sept. 13 concert by Miley Cyrus on morality grounds. The commission said in a statement that it took the action because Cyrus often undertakes acts that go against moral acts and customs that often which are punishable against Dominican law. Tickets for the concert, some as much as $350, have been on sale since July. Some critics have declared Cyrus’ onstage antics, including twerking, as vulgar.
