The man who had won it all in Superstar K, Seo In Kook is now gearing up for his next album, scheduled to drop at the end of April. His first album, which he was able to release as his prize of winning first place in Superstar K, has come and gone much unnoticed than anticipated, but was still able to rank relatively high in music charts. For a fresh new start, Seo In Kook has undergone a drastic change in appearance, as he confirmed that he has lost over 15 kg (around 33 pounds). The fans couldn't help themselves but to awe in shock by the noticeable difference when a new picture of the star was uploaded on his freshly-made Twitter account, looking slim and sharp. On top of that, a snapshot was unveiled recently by a Thai fan who spotted the "skinny" Seo In Kook in Phuket, Thailand, where the singer visited briefly for a music video shoot. Seo In Kook also tweeted out a thankful message to his fans, "Thank you to those who are concerned about me. I am putting in my very best efforts for my upcoming album release, so please look forward to it."
