Is there another film with a similar plot?

I LOVED this film and it is brillianty executed but I can't help think I've seen a similar plot before when a guy hires someone to be his girlfriend for his family's sake and then falls for them.

All I can think of Debra Messing in the Wedding Date but thats not it.

Anyway won't be long before Hollywood takes this script and turns into a vanilla, bland, sterile rom com.
