It has recently been revealed that member Lee Youngjun of rookie idol group Big Star has lost over 30 pounds in just two short months.

Youngjun's before-and-after photos (above) were posted on an online community site with the caption, "Is this really Big Star's Youngjun? Explosive weight loss."

Different from his beastly, masculine image now, Youngjun was once a bit chubbier and had a more innocent look.

A representative from Big Star's agency Brave Entertainment remarked, "Youngjun is full of passion and ambition. In order to become a member of Big Star, Youngjun lost over 30 pounds in just 2 months. He is getting popular with the ladies and they've already created internet fan cafés, thanks to his appearance that resembles singer Rain, as well as his fluid dance skills."

Netizens who came across his photos responded saying, "He must have worked so hard", "He did change a lot", "How did he get that new body?", and more.
