Aida Nikolaychuk

Aida Yurijivna Nikolaychuk, sometimes spelled Nikolaichuk, (Ukrainian: Аїда Юріївна Ніколайчук) is a Ukrainian pop singer and model, who was the winner of the third season of Ukraine's X-Factor TV talent competition in 2012. She drew special attention during the show's second season when judges interrupted her performance of Polina Gagarina's Lullaby (Колыбельная, Kalybelnaya), suspecting her voice was actually a digital recording. They challenged her to sing the song a cappella. Although visibly surprised, Nikolaychuk sang the song equally well without accompaniment. In 2013, she released her first single, "On Your Planet", which was included in her debut album "We’re under one sky".
