Baek Ah Yeon's transformation has caused a sensation.

This week's ‘K-Pop Star,’ the top 7 contestants battled fiercely under the theme of ‘Soundtracks from movies/dramas.’

Baek Ah Yeon had picked the song 'Can't Fight The Moonlight' from the movie ‘Coyote Ugly,’ showing off her sexy charms. She even flaunted some dance moves using a chair to further accentuate her sexy charms. Although the show was eye catching, it was less than what she had done last week.

BoA commented, "The problem with this performance was that it wasn't fully yours. If I were to cast you today, I would have to teach you to be provocative. Although I honor the attempt at change, your high notes were a bit all over the place." She awarded 85 points.

Yang Hyun Suk commented, "Although I applaud you for trying something new, I think it's critical that you stick to something you're good at rather than gambling with uncertainties." He awarded 82 points.

Park Jin Young commented, "In order for someone to score about 90 points, there has to be perfect stability. But I felt your anxiety. But I was pleasantly surprised by your dance skills." He awarded 99 points.

The top 6 contestants will be divided into SM, JYP, and YG by the three judges and will receive special training for a week.
