Hmm. Does it have to be a Hollywood actor/actress? If yes, then Ming-Na is my definite choice. She's Asian-American like me, and I think she's a decent actress.
If no, then South Korean actress, Song Hye Gyo, is my first choice. She's lovely to look at. I wish I was half as lovely.

Not to mention, she can act very well.
