You are the Apple of my Eye is a Taiwanese Film that was a hit in Hong Kong last year.
The expression is quite a common one in English. The original expression dates back to the bible and its first recorded use in Old English was in the 9th Century. It is perhaps best known from the lyrics of Stevie Wonder’s You are the Sunshine of My Life (which has recently been used in a local ad for McDonalds (perhaps explaining the McDonalds-related imagery).
I also like this song by Bell XI—Eve, Apple of My Eye:
There are a few different songs with the title Apple of My Eye.
Regarding the other names, Jay Chou is, of course the famous Taiwanese pop singer, Avril Lavigne the Canadian pop star and Gigi is one of our students (maybe the apple of a few different pairs of eyes!)
