A lot of people might think that being an idol is all about fame, glamor, fans and other luxurious privileges. Perhaps, we don't know that there's a lot of sacrifices that someone makes in order to be one of the most successful idols in the entertainment industry. The latest episode of "Happy Together 3" featured AOA's Seolhyun, who unveiled the other side of an idol's life that would make everyone thinks millions of times before deciding to be one.

AOA's Seolhyun was invited to a variety show "Happy Together 3". According to Korea Boo, during the broadcast, the AOA idol spilled one particular thing she hates the most about being an idol: dieting. Seolhyun is, in fact, not a person who can commit one hundred percent to dieting. The singer admitted that she loves food in general and even craved for more when she was a trainee. However, she had to watch her weight and the food intake on a daily basis, and that sometimes made her pretty much suffering to the point she even considered to leave her group.

What makes it even terrifying is Seolhyun's confession about her misery to commit with her diet. The hardcore fan of Girls' Generation's Taeyeon admitted that there were times when she didn't record what she ate or her weight. When that happened, she would cry while eating because deep down, she knew that she would get into trouble if she gained her weight. Seolhyun's confession about the diet strict requirement as a trainee clearly surprised everyone, including her fans. However, "Happy Together 3" was concluded with a happy ending when a video of Seolhyun eating happily showed up.

Asides from her surprising confession on "Happy Together 3", Seolhyun recently was featured for LG Fashion outdoor brand, Lafuma, along with ASTRO's Cha Eun Woo. The two idols look fit and adorable in a video ad campaign that you can watch below.
