Asian Pop Princess

On Vietnamese television, Jun Phạm performs as Thanh Thảo. The big pop transformation occurs at about the 2:40 mark.

 

The video has at least temporarily left  YouTube, but there are many photos here, including this one after the change I mentioned:

The fall season of "Your Face Sounds Familiar" has not been the best around the world. I think the top performers have appeared on Gương Mặt Thân Quen, which is the Vietnamese edition of the show. The season started earlier in the year and extended into fall.

Bach Công Khanh

The performance of "Depend on You" starts around 5:15.
