Lee Chae-yeon

On October 18, 2021, after a three-year hiatus, Lee made a comeback with the ballad single "Sometimes I Cry".

On June 1, 2020, Lee released the single "Pink Monster (핑크몬스터)".

On August 20, 2019, her agency Cai Entertainment announced that she will be releasing a new song monthly until December. Her new single "Empty Heart (텅텅빈맘)" was released on August 20, 2019. On September 10, 2019, she released the single "Fly High".

In 2018, she made a comeback with the single "Bazzaya".

On October 17, 2016, she signed with A9 media. She had been promoting mostly in China for a while, so through this label, Lee began promoting actively in Korea through variety shows, dramas, and musicals.

In 2015, after a five-year hiatus, Lee made a comeback with the single "Obvious".

On July 22, 2010, Lee made her comeback on M! Countdown. She performed "Crazy" and "Look Look Look" from her new album. It was well received by fans. She continued to perform on various music programs and promote her album. Her second mini album "Look at" was released on July 29, 2010.

On December 8, 2009, Lee had her first live mini concert in China. She performed her songs to a sold-out crowd.

In addition to promoting her album, Lee joined the cast of Hi-Five, part of KBS's Happy Sunday line-up. On the reality-variety show, which also starred Hyun Young, the stars attempted to succeed in various tasks, including starring in a musical, becoming flight attendants, and performing action movie stunts. She remained a part of the show until its cancellation in 2008.

Although briefly hospitalised due to exhaustion, she made her comeback at the end of March 2006. Her lead single from her fourth album was "My Love", which was a Latin-tinged dance song. The single was extensively performed, with a remix promoted from May onwards; she then followed up with "Clumsy Love (서투른 사랑)". The album sold 12,346 copies in 2007, placing 68th for the year. She continued to remain a "sexy" singer, saying that she does not mind the label.

She returned after a brief break to release her third album III, which came in the fall of 2005. The first single, "오직 너", fared poorly on the charts. The record company then quickly switched to the "Disco Mix" of the song, which helped sustain its life on the charts, although not by much. The second single, "Third Love (세번째 사랑)", also fared poorly. However, this can be attributed to the fade of sexy R&B music in Korea at the time, as ballads were once again the style of choice for Korean singers.

Lee has continually participated in variety shows such as SBS's X-Man and Love Letter. She ended her official schedule with her last X-Man episode on September 25, 2005, to concentrate on recording her fourth album.

She returned to Korea with her first official album It's My Time under her new stage name, Chae Yeon. Initially, she was simply viewed as yet another "sexy concept" singer, as many female singers were at that time. Her debut song "위험한 연출" ("Dangerous Presentation") did well, but her real success came when her second album released late in 2004. "Two of Us (둘이서)", the lead single, pushed her to No.1 on many music charts in the spring of 2005. The music video for "Two of Us" was controversial for being too "racy" in conservative Korea, as it contained scenes showing her full back and exposed underwear. Subsequently, the video was banned on television, and the airing time was limited to after 10:00 p.m. on some cable channels. Becoming heavily played on radio, the song became so popular that a signature move from the choreographed dance became known as the "Na-na-na" dance, named after the hook of the song. It managed to hit the top of various music charts in Korea. The follow-up single "Come to Me (다가와)" was released soon after and was also popular, riding on the wave of its predecessor.

Lee originally began her career in Japan as part of Brand New Biscuits [ja](ブランニュービスケット), debuting in Japan on January 1, 2001, as part of a six-member lineup. Brand New Biscuits included also another Korean singer, Yuny Han. Lee was also member of the group UltraCats (ウルトラキャッツ) under the name of "Jinny" (ジニー) or "Jinny Lee" (ジニー・リー) from 2001 to 2002.

Chae-yeon Lee (Korean: 이채연; born Lee Jin-Sook (Korean: 이진숙, Hanja: 李珍淑); December 10, 1978), best-known mononymously as Chae Yeon, is a Korean pop singer who rose to fame with her hit single "Two of Us" (Korean: 둘이서) in 2004.

Lee was born in Seoul on December 10, 1978. She is a graduate of the Department of Broadcasting & Entertainment, Seoul Arts College. Her family consists of her parents and her older brother.
