It's been less than three months since her debut but singer Ailee is already taking the Korean entertainment scene by storm with the commanding stage performance of a veteran entertainer. Ailee is a Korean-American artist who debuted in February with her single "Heaven."

Her playfulness backstage vanishes as soon as she appears in the floodlights. "For some reason, I turn into a different person when I get on stage," Ailee said. "I don't get stage fright. For me, it's fun." Ailee became a star on YouTube before she debuted on Korean TV. Around 10 clips of her singing for her own entertainment that she uploaded on the video-sharing website registered a total of 10 million visits. That feat led to her appearing in a talent contest on NBC's "Maury Show" in 2008, where she finished in second place. "People told me I was a good singer, so I became curious to find out just how good and decided to upload the clips for fun," Ailee said. "I posted several more clips after I received a lot of messages asking me to do so." She says an American music producer approached her about a record deal, but she turned down the offer. "My parents and grandparents, who went to the U.S. from Korea, always told me that I am Korean and made me speak Korean at home," Ailee said. "I am Korean, so I naturally wanted to go to Korea to sing… I'm big fan of K-pop so I formed a band with other Korean-Americans and we performed here and there." She took time out from her university studies and came to the country in 2010 to become a singer. "I'm still learning about Korea and how to express myself through my music here in a way people can fully relate to, but I am practicing hard and hope to move others through my singing," Ailee said.
