When Miley Cyrus transformed herself into Hanoi Montana for this photo -- she had to know it would turn into bad fortune.
The OCA -- a group "dedicated to advancing the social, political and economic well-being of Asian Pacific Americans" -- is fuming at this photo of Miley and pals for using what they have deemed an offensive, stereotypical gesture.
The OCA sent us this statement: "The photograph of Miley Cyrus and other individuals slanting their eyes currently circulating the Internet is offensive to the Asian Pacific American community and sets a terrible example for her many young fans. This image falls within a long and unfortunate history of people mocking and denigrating individuals of Asian descent...
"OCA hopes that Miley Cyrus will apologize to her fans and the APA community for this lapse in judgment and takes the opportunity to better understand why the gesture is offensive."
