Kim Hyung-seo, better known by the stage name BIBI, is a South Korean singer-songwriter. In 2017, she signed with Feel Ghood Music after Yoon Mi-rae discovered her self-produced songs on SoundCloud. She appeared as a contestant in the SBS show The Fan, where she eventually finished in second place. She made her official debut through releasing a single "Binu" on May 15, 2019. In April 2021, she released her second extended play Life is a Bi.... In October, she released collaboration single "The Weekend" with 88rising. It later peaked at 29 on the Mediabase Top 40 chart, making Bibi the first Korean female soloist to do so. In December, she signed a global promotion deal with 88rising. On November 18, 2022, she released her first studio album Lowlife Princess: Noir. Bibi pursues freewheeling and out-of-the-box music. Her music features various genres, including R&B, soul, hip hop, and ballad. Rather than focusing on dealing with beautiful things beautifully, it is a style of music that focuses on beautifully sublimating beautiful sorrows and pains that are alienated and hidden from the world. She gets inspiration from her experience and feelings. She was influenced by Nicki Minaj because of her "pop tendency and ability as a rapper".
