"I'm sick of her behavior," says one of Mai Phuong Thuy's fan. "In my opinion, Miss Vietnam or Miss Whatever should behave in a proper way. I admired Thuy for a while because I thought she was nice and clever. However, she has become less and less likeable to me since I found out that she uses bad language, that she is dating several guys at the same time, that she affiliates with the ill-mannered people..."

Are these words just from a disappointed fan or has Miss Vietnam really changed her manners?
