Her acting isn't all that good from what I've seen. She should definitely stick to her day job and keep at it with the singing. She's already got a pretty packed schedule with singing, tons of commercial endorsements, photo shoots and her clothing line. There are actually more Asian actors and actresses nowadays (and a LOT of mixes are out there) but to be bankable in the US they need to speak English well and/or do action movies if they don't speak it.
