If you were a K-Pop fan in the late 2000s, there’s one child you probably still remember clearly: Jung Yoogeun, the adorable baby who completely stole the spotlight on Hello Baby with SHINee.
More than a decade later, fans are doing double takes after seeing just how much Yoogeun has grown and the nostalgia is hitting hard.

When Hello Baby aired in 2009, Jung Yoogeun quickly became the heart of the show.

From his tiny size and chubby cheeks to his sweet smile and playful personality, he was impossible not to love.

Viewers watched as SHINee took on the role of “parents,” feeding him, playing with him, and doting on him like real family. Yoogeun’s innocent reactions, unexpected sass, and natural chemistry with the members made the show unforgettable.
Now, years later, Jung Yoogeun is no longer the toddler fans once knew. He has grown into a teenager with noticeably taller height, more defined features, and a calm, mature aura that has shocked longtime viewers.

Despite the years, many fans note that his gentle expression and warm energy remain the same—making the transformation even more touching.

He has stepped away from the spotlight.
