Song Ji-hyo showed off a completely different hairstyle.

In SBS 'Running Man' broadcast on the 28th, Song Ji-hyo's hairstyle became an issue.

On this day's broadcast, Yoo Jae-suk mentioned Song Ji-hyo, who suddenly cut her hair short, saying, "Song Ji-hyo's short haircut is the biggest issue."

Jeon So-min drew attention by saying, "Ji-hyo unnie finally decided to buy her brother's heart."

Then Jeon So-min said, "It's Eun-chan's style that Yoon Eun-hye did in 'Coffee Prince'," and Yoo Jae-suk agreed, "I think it's true to some extent after hearing So-min's story."

Then Kim Jong Kook said, "Didn't you cut it after seeing Demi Moore older sister?"

Jeon So-min once again insisted, "No, 'Coffee Prince' Yoon Eun-hye's older sister."

In the end, Song Ji-hyo, who could not see this situation, said, "What a bullshit! Be quiet," and made everyone laugh by blocking his brother's mouth.
