Seo In-young reveals strict egg diet ahead of Waterbomb comeback
Singer Seo In-young prepares for her major stage return at Waterbomb Sokcho 2026, revealing her intense weight loss and physical transformations.
Singer Seo In-young is drawing public attention once again as she prepares to return to the big stage after a long hiatus. Having navigated the ups and downs of marriage, divorce, and a hiatus from professional activities, she expressed her determination to once again demonstrate her unique stage presence through 'Waterbomb Sokcho 2026'.

In a recent interview video released through Waterbomb's official SNS, Seo candidly shared her excitement and nervousness ahead of her performance. In the video, she appeared with long wavy hair, a white T-shirt, hot pants, and boots, showcasing a slimmer physique and her undiminished sense of stage presence.
“I waited for this so much. It was so good to see [the stage] again,” she said, sharing her feelings about standing before the public after a long time, adding, “It is time to show them now. I have prepared many things.” In particular, she revealed that she put significant effort into her physical transformation for the stage, stating, “I spent a lot of money on management and procedures.”
The core of the stage Seo is preparing is, predictably, 'classic Seo In-young intensity.' She teased her signature provocative performances, saying, “A stage that is uniquely Seo In-young; I’ve even prepared high high heels.” She raised fans' expectations by preparing a parade of hits, including cover stages for 'Baby One More Time,' 'Cinderella,' and 'Jewelry Superstar,' alongside her own representative hits like 'I Want You' and 'That Dance in the Rhythm.'
This stage is special because it carries more meaning than a simple return to performing. Since her appearance on MBC's 'King of Mask Singer' in 2021, Seo has effectively reduced her official activities. Following personal changes such as marriage and divorce, she distanced herself from the public, and until last year, her name was primarily discussed in relation to her past activities.
However, she began communicating with the public again this March by launching the YouTube channel 'Gaegwacheonseon Seo In-young.' This Waterbomb stage is expected to serve as a new starting point for her, as it is her first major performance following the long hiatus.
The method Seo chose ahead of the stage was thorough self-management. Through YouTube, she revealed her weight loss process, stating, “I don't eat much these days,” and confessed that after dropping to 46kg, she gained 4kg back. In particular, her story of managing her body by eating boiled eggs instead of rice drew significant interest from fans.
She did not hide her physical changes either. Seo directly disclosed undergoing facial laser procedures and arm liposuction, even candidly mentioning the aftereffects, such as "my facial expressions don't work well." Her decision to reveal the efforts she made to create a perfect stage and the difficulties she faced in the process has been evaluated as a move typical of Seo, who was known for her honest and unrestrained image in the past.
Seo is a star who once played a major role in pop culture with her 'trendy woman' and 'tough girl' image. Representing the music industry of the 2000s with her intense fashion, unique performances, and confident character, she now seeks to take the stage again with a different side after the passage of time.
Behind the glamour lie a hiatus, changes, and the will to start anew. The Waterbomb stage is likely to be more than just a recreation of past glory; it will be a stage where Seo, having passed through the curves of life, proves her name once again.
'Waterbomb Sokcho 2026' will be held on August 22 at Hanwha Resort Seorak Sorano, featuring various artists including Rain, Tiger JK, Mirae, Simon Dominic, and Lee Young-ji.
