On January 9, 2026 (KST), Soyul posted several photos of Moon Hee Yul along with the caption, “Our Jam-ie’s Christmas concert.”
Our Jam-ie’s Christmas concert. Once again, it was so moving and beautiful… She performed so well and looked so lovely. I’m so proud of you. I love you.
— Soyul
Soyul’s photos captured the 8-year-old Hee Yul in her international school uniform. Once affectionately nicknamed “Jam Jam” on The Return of Superman, the idol couple’s star baby—who received immense love from viewers at the time—caught attention with her noticeably grown-up appearance!
