Güllü, whose real name was Gül Tut (October 15, 1973, Kasımpaşa – September 26, 2025, Çınarcık), was a Turkish fantasy and arabesque music singer of Romani origin. She began her musical career at a young age by singing in nightclubs. In 1988, at the age of 15, she performed in wedding halls. Since she was underage, it was not possible for her to work in music halls, so she continued her education for a while. However, due to her family’s financial difficulties, she dropped out of school and pursued singing. In the 1990s, she became known as “Kasımpaşalı Güllü.” She gained recognition with Romani-style songs and her released albums. After getting married, she took a break from performing for some time. She had two children. Following her divorce in 2000, she returned to her music career. In 2008, she was hospitalized in Kartal Yakacık after falling into an alcohol-induced coma, and was discharged following treatment. On September 26, 2025, she died after falling from the balcony of her home in Çınarcık, Yalova.
