SISTAR will be holding a reunion stage on the final episode of KBS2's 'Yoo Hee Yeol's Sketchbook'. 

Earlier this week, KBS2 announced that the late night music program 'Yoo Hee Yeol's Sketchbook' will be coming to an end with its 600th episode, after MC Yoo Hee Yeol expressed his desire to leave the show. Yoo Hee Yeol, currently facing criticism due to a series of music plagiarism controversies, recently confirmed his intentions to leave all of his programs and halt his activities temporarily. 

Soon after the news that 'Sketchbook' would be coming to an end, it was also reported that the final guest lineup for the 600th episode of the program would include stars including Paul Kim, MeloMance, 10cm, Daybreak, Kim Jong Kook, Oh My Girl's Hyojung and Seunghee, Hyolyn, Gummy, and Heize. 

But now, according to media outlet reports on July 19, one of the guests on the 600th episode of 'Sketchbook' will be not just Hyolyn, but all four members of SISTAR. 

This will mark SISTAR's first ever reunion stage since their official disbandment in 2017. 

The final episode of KBS2's 'Sketchbook' featuring SISTAR's reunion stage will air on July 22.
