BLACKPINK‘s Jennie has opened up about how hectic the girl group’s lives were the first three years after their debut.The K-pop idol recently sat down with Rolling Stone as part of the girl group’s special cover edition with the news outlet, during which she recalled BLACKPINK’s first three years together and how they had “worked nonstop without resting” at the time.“I became sick, both mentally and physically, after the last world tour ended [in 2020],” she shared, before adding that she wanted to be as “vague” as possible about the details, as this wasn’t something she wished to share with fans in too much detail as they might worry.“For three years after debuting, we worked nonstop without resting,” Jennie added. “Our sleep systems were breaking down; we weren’t eating properly; I wasn’t hydrating myself – we did that for three to four years, and then started our tour.
