Actress Song Ji-hyo is making waves once again—this time not as a fashion CEO but as a full-blown foodie queen.

On the June 29 broadcast of SBS's variety show Running Man, Song delighted fans with her unexpected yet hilarious transformation into what cast members dubbed the "new mukbang queen."

Her carefree attitude during a buffet challenge led to a now-viral moment where she unzipped her pants on camera, laughing, "Making room in my belly!"

The scene came just six months after Song made headlines for launching her own underwear brand and modeling the debut collection in a sultry photo shoot.

Her bold images at the time earned her nicknames such as the "Korean Kim Kardashian."

However, on this week's episode, Song's figure wasn't the focus—her appetite was.

"I thought Ji Hyo was just slowly enjoying one churro... but when I looked again, she was already on her third," castmate Haha joked.

"Now that Ye Eun is dieting, Ji Hyo is filling her place," added host Yoo Jae-suk. "She's the rising star in the new food champion lineup."

Kim Jong-kook also chimed in, teasing, "These days, it's like Ji Hyo's the one stealing Ye Eun's food.

She keeps getting bigger while Ye Eun's shrinking." Song coolly responded, "Bulking up is a talent too."

As the buffet mission escalated with the arrival of grilled pork belly, Song casually unzipped her pants, drawing cheers and laughter from the other cast members.

When Ji Ye-eun admitted she had also unzipped hers earlier, Yoo Jae-suk declared, "It's the ultimate showdown: new mukbang queen vs. the OG!"

Song's unfiltered and relatable moment quickly gained traction online, with viewers praising her down-to-earth humor and willingness to break from her glam CEO image.

While she may have conquered the lingerie world, it seems Song Ji-hyo is also winning hearts at the dinner table—one pork belly bite at a time.
