US singer Madonna performs on stage during her concert at Izvor Park in Bucharest, Romania, 26 August 2009, as part of her 'Sticky and Sweet Tour'.
Madonna was booed during her concert in Romania's capital Bucharest after she declared herself against the discrimination of Roma in Eastern Europe.
The pop star made a pause during her concert Wednesday night in order to speak out for the Roma saying the Roma were discriminated against in Eastern Europe, which made her sad because no one deserved to be discriminated.
The audience booed her because of her statement but Madonna did not react to those negative signs, BGNES reported.
Several Roma musicians and a Roma dancer took part in Madonna's concert in Bucharest. Her concert in Sofia is scheduled for August 29, 2009.
