Everyone's talking about singer Kim Bum Soo's second double eyelid cosmetic surgery.

On the September 18 episode of MBC's Korean Thanksgiving special of "I Am a Singer," Kim Bum Soo starred as a guest wearing a pair of sunglasses, and manager Park Kyung Rim brought up his recent double eyelid surgery. To that, he replied, "I'm very happy with the outcome. My condition right now is the best it's ever been" and showed confidence in his decision.

Park Kyung Rim seemed a little taken aback and cautiously commented, "Oh, there is still about 30% swelling that needs to go down." Kim Bum Soo was still confident, and said, "If senior Insooni tells me to take my sunglasses off, then I will." Then he boldly took off his sunglasses among his fellow singers.

But the response from the others was quite different from that of Kim Bum Soo, and there was a moment of laughter. Even the other guests appearing as managers couldn't help but say "It's alright," which elicited laughter once again.

On this episode of "I Am a Singer," YB, Park Jung Hyun, Kim Kyung Ho, Kim Bum Soo, Park Wan Kyu, Yoon Min Soo, Insooni, and Jang Hye Jin battle it out to become the winner.
