Weight Loss Tips


Gayoon has been showing a differences on her body. She lost weight, and it seems like way too much. Gayoon was reported to have lost about 8kg, or almost 18 pounds. The picture above shows Gayoon’s thinner body, which is making fans worried and catching attention.

When she was asked about her changing body, she said, “If you dance ’24/7′ just two times, you start sweating a lot. That is why we said among ourselves that ‘Volume Up’s choreography was easy [compared to ’24/7’].”

She explained,”We really sweat a lot. I want to start an aerobics center with Jiyoon and let people know about it. Compared to my promotional activities for ‘Volume Up’, I lost 8 kg (~17.6 lbs.). All of my pants are big right now. All of my outfits don’t fit. I have to get them resized. Even the smallest size clothing and pants, I have to tailor the sleeves and wear it.” However, to assure fans that may be worried, she commented, “There is nothing wrong with my health. You don’t have to worry.”

The main vocal of 2YOON then also stated, “Although there are fans who worry about our health, we are exercising and managing our diet so you don’t have to worry. We are very healthy.”

Plastic Surgery Rumor


4minute‘s Gayooon has been getting attention of her new, pointy v-line chin.

Gayoon  wore a fancy, flower-print jacket when she attended the fashion brand “Oz” Second Launching 15th Anniversary Exhibition at the Beyond Museum at Seoul, Gangnam, on August 30 with her fellow 4minute member, HyunA.

If comparing an older photo of her to a more recent one, her chin is looking sharper. Since Gayoon had a cute image with a round face with prominent features, this new feature is qite obvious because it gives her a sharper face.


Gayoon also reportedly had blepharoplasty to give her double eyelids, a procedure that is done commonly by Korean people. Obviously, her eyes looked much wider and bigger after the surgery, if comparing two pictures above.


Gayoon also seems to have had her nose operated on. Before, she had a short, fleshy nose in the first picture, and if comparing to the second picture, it now shows a sharper tip and a high nose bridge.

4MINUTE’s Disbandment and Future Activity


On June 13, 2016, Cube Entertainment announced that 4Minute decided to disband, but at the time, the members were still discussions to renew their contracts. Unfortunately, on June 15, 2016, Cube Entertainment officially announced that Jihyun, Gayoon, Jiyoon, and Sohyun’s contracts had ended on June 14, and they decided not to renew.
