Returning idol Jay Park has lost a bit of weight lately. He revealed that fighting a case of the flu along with rigorous dance practice had previously brought him down from his usual 62kg (137lbs) to a very low 50kg (110lbs). On top of his already hectic schedule, the talented singer is apparently sleeping only 4 hours a night as he is still recording for the upcoming movie Hype Nation. He also expressed his nervousness about performing solo in his upcoming tour, set to land in Hong Kong, Taiwan, Singapore, and the Philippines. "There's a good side to being able to decide the style for my hair, clothes, song, and dance on my own, but the idea of singing everything by myself and getting the audience hyped up is daunting. I'm still happy to be standing on the stage though." Fans shouldn't worry too much as his current weight has bulked up back to 58kg (128lbs). Source: Hankooki
