Jhené Aiko Efuru Chilombo (born March 16, 1988) is an American singer and songwriter. She embarked on her music career contributing vocals and appearing in several music videos for R&B group B2K. At the time, she was known as B2K member Lil' Fizz's "cousin", though she is not actually related to him. It was used as a marketing tool, suggested by Sony and Epic Records, to promote Aiko through B2K and attract an audience. In 2003, Aiko was set to release her debut album, My Name Is Jhené, through her labels Sony, The Ultimate Group and Epic, however the album was never released, with Aiko asking to be released from the label in order to continue her education.
