Detect Facebook language

Question

I'm working on a Facebook application where there will be 2 languages, obviously the user can switch himself, but I would also like to detect what language the user is using on Facebook so I can set that as a default one.

I checked the opengraph API, but there doesn't seem to be any way to detect this, are there any other options?
