I randomly found this video of Corinna singing in Cantonese, and I'm really impressed! For those of you who do not recognize her, she's a TVB actress who mainly has a few small roles who plays the foreigner when needed. She has a bigger role in the Roger Kwok/Joey Meng/Wong Cho Lam comedy, Cousin, You Are Good. Her Cantonese is really good, much better than a lot of newcomers from Miss Hong Kong. :P
Go check out her other videos here: Youtube Channel and tell me what you think!
