On June 25th, KBS 2TV's music talk show 'Yoo Hee Yeol's Sketchbook' aired their episode featuring Big Mama.

Big Mama recently returned with their new single 'One More Day', after 9 years. On this day, Big Mama performed their song with powerful, harmonized vocals, and then took some time to share a conversation with MC Yoo Hee Yeol. Yoo Hee Yeol went around asking how each of the members have been doing and when it was Lee Young Hyun's turn, Yoo Hee Yeol commented, "Lee Young Hyun really succeeded. I remember seeing you during the peak of your career. You have lost a significant amount of weight."

To this, Lee Young Hyun laughed and replied, "The last time you saw me was probably when I was at my heaviest. I did lose over 30 kg". She continued, "I had an extremely difficult time during my pregnancy due to my diabetes. I thought to myself that if I continued living like this, I would die early. So in order to really find myself, I worked hard to diet."
