Hyorin revealed her beautiful mother, who received compliments from those on set as she surprised them with her youthful appearance.

The SISTAR member brought her mother onto the Lunar New Year special 'Mama Mia'. Her beauty awed the cast, and the MCs couldn't help but point out how young she looks. Hyorin's mother revealed, "I got married when I was 22. My age is probably around Kim Yong Man's." In response, Kim Yong Man said, "I was born in 1967." Hyorin's mother revealed, "I was born in 1970."

She turned out to be younger than MC Hong Rok Gi, who was born in 1969. Regarding her looking so young, Hyorin added, "If my mom wears normal clothes, she looks even younger. We wear the same clothes and we shop together. When we walk around together, she looks younger."
