On the January 27 episode of SBS variety show 'Running Man,' actress Jung Yoo Mi bravely confessed just how much of a Yoo Jae Suk fan she is. 

During the broadcast, cameras caught her being visibly nervous when seeing him in person for the first time. When Yoo Jae Suk went to greet her, she took a slight step back.

She then explained her unusual behavior by confessing that she had been a huge fan of Yoo Jae Suk, surprising the MC by saying "I really wanted to meet [you]."

Fellow 'Running Man' castmate Lee Kwang Soo, who has had a close friendship with the actress for roughly a decade, backed up her statement, adding: "She has been a Yoo Jae Suk fan for a really long time."

"Honestly, when I heard you got married, I cried really hard," she confessed. "Yoo Jae Suk getting married was the saddest thing that happened [to me] after Brad Pitt getting married."

Meanwhile, Jung Yoo Mi joined fellow guests Lee Yoo Ri, Hong Jong Hyun, BIGBANG's Seungri, AOA's Jimin and Mina for Running Man's 'Level Up Project Final' episode.
