On 19 December 2013, Brena, along with Dragana Mirković, Severina, Jelena Rozga, Haris Džinović, Aca Lukas and Jelena Karleuša, was a guest at a humanitarian concert by Goran Bregović at the Olympic Hall Juan Antonio Samaranch in the Bosnian capital city Sarajevo for the Roma in Bosnia and Herzegovina. Brena arrived in Sarajevo two days before the concert so that she could enjoy the city with friends before the concert. She said in an interview: "Sarajevo has suffered and survived so much, I'm really glad to see positive people and happiness in this city".
