My Little Old BoySo, who is Kim Jong-kook’s wife?

On the Sept. 7 episode of SBS’s "My Little Old Boy," Kim Jong-kook teased that he’s finally ready to share his love story.

In a preview at the end of the show, the newlywed is seen meeting HeeChul and Kim Dong-hyun.

Fans long joked he’d “marry the gym,” so his surprise wedding announcement drew a wave of congratulations.

“She might be heavy on the wet wipes. Guess you can't nag anyone about that anymore, isn't that right?” HeeChul joked. Kim laughed, replying, “Well, I'm mentally prepared,” hinting at a shift in his routine.

When Kim Dong-hyun warned that workouts could spark tension at home, Kim admitted they’d already argued once over his training schedule.

HeeChul then rattled off the internet rumors about Kim’s wife ― from being L.A.-born to a cosmetics CEO. “I’ll tell you exactly,” Kim said, promising to separate fact from fiction and fully clear the air on the next episode.
