TV show breakout MIMI made a lively stop on SBS’s "My Little Old Boy" as the special MC on the Sept. 14 broadcast.

She treated the show’s panel of celebrity moms to a quick OH MY GIRL dance, prompting HeeChul’s mother to marvel, “Once an idol, always an idol.”

Seo Jang-hoon joked she’s “on another level―like a TV show pro who just happens to crush choreography,” drawing laughs.

Fresh off her Best New Female Entertainer win, MIMI shared that Yoo Jae-suk was the first to text his congratulations―something she said she was deeply grateful for.

Shin Dong-yup quipped that he meant to send a message too but didn’t have her number, keeping the studio in stitches.

The episode also spotlighted MIMI’s wholesome, sweet-goofy charm―earning her the “young, female Kim Jong-min” comparison―and viewers took notice.
