Rumor: Cho Chang casted

[hunao01 at yahoo.com]

I didn't find anybody report this, maybe most people here already 
knew. Anyway, here it goes:
>From Mugglenet:

"Cho Chang will be played by fourteen year old actress Sarah Lee. 
Sarah lives in Sussex and is currently attending Hastings Stage 
Studio, a dancing school in Sussex. She lives with her English 
parents, but her grandparents were Chinese which made her perfect for 
the part."

How could somebody has "English parents" but "Chinese grandparents"?  
Does this mean her parents are U.K. Citizen but her grandparents are 
not? Or one of her parents is white? Or she was adopted? It's really 
confusing.

Anyway, she is 2 year older than Dan. This shouldn't be a big problem 
but Cho is kind of short. Hope Dan will be tall enough when the 3rd 
movie filming begins. Wish she is good looking too. I don't want a 
mini-Lucy Liu (no offense to Ms. Liu.I just don't think she is pretty)
