The career journey and famous songs, MVs of Giselle

Giselle’s career journey before and after debuting with the South Korean girl group aespa has always been of special interest to fans. Specifically:

Before Giselle debuted with aespa

Before debuting with sespa, Giselle was trained at SM Entertainment for about 11 months. Additionally, during her training, she often wore a headband, leading her trainers to compare her to a British girl. This idea inspired her to come up with the elegant stage name “Giselle” for herself. Giselle was also a member of the St. Mary choir for 4 years, serving as an Alto.

On October 28, 2020, in a video introducing the final lineup of aespa during a press conference, Giselle was revealed as a member of the group. She was officially announced as a member of aespa by the company on October 30. The group officially debuted on November 17, 2020, with their debut single titled “Black Mamba.”

Scandals/ Controversies

Upon SM Entertainment’s announcement of Giselle as aespa’s fourth member, she faced backlash, with some questioning her short training period and criticizing her appearance. Allegations surfaced online regarding her past, including claims of delinquency and substance abuse. However, a childhood friend defended her, attributing her lack of contact with Japanese friends to a busy schedule. The friend also dismissed party photos as manipulated. Concrete evidence supporting either side is yet to emerge.

Furthermore, Giselle’s family background has also become a hot topic on social media. Some users rediscovered a post showing renowned journalist Cho Joo Hee thanking her granddaughter named Aeri (matching Giselle’s real name) for sending a cake from Tokyo, Japan. The coincidence of name and location sparked rumors that Giselle is Cho’s relative, a significant figure in the Korean entertainment industry and a long-time rumored partner of the SM Entertainment chairman. This detail added fuel to the speculation that Giselle’s debut was facilitated by her family connection.


In October 2021, Giselle once again became the center of criticism when she became embroiled in a controversy involving racial discrimination. In a behind-the-scenes clip of aespa dancing and singing along to the song “Love Galore,” as the only one who knew the lyrics, Giselle casually sang along but failed to realize she sang a line containing the “N-word.”

Not long after one controversy, a topic about Giselle continues to attract attention on Korean social media. Netizens are debating a detail in a Vogue video where aespa visits New York at the Empire State Building. Giselle was seen holding her phone, looking down, and saying, “I would die if my phone drops.”
