Baek Ah Yeon revealed how she upgraded her look for her debut.

The singer recently made her debut with "Sad Song", and people have been amazed at how much more beautiful she has become. Baek Ah Yeon stated that she didn't have cosmetic surgery, but got her teeth laminated instead.

The singer said, "I was called out by Yang Hyun Suk about my front teeth.  Afterwards, when I signed on with JYP Entertainment and was preparing for my debut, I got some work done on my teeth. I fixed my teeth at the agency's dentist."

She added, "Before my debut, I went on a banana diet and also worked on my appearance."

After seeing her performance of "I Miss You" on 'K-pop Star', YG Entertainment CEO Yang Hyun Suk commented, "I'm trying to think of what Baek Ah Yeon is lacking. Her musical tone is great and so is her appearance. The only thing is that her front teeth stick out a little in a cute way. If she ever fixes her teeth, she will be perfect."
