Just Watched This Great Movie Again for the Umpteenth Time

I am currently doing a local radio quiz and there is a snippet played from a 'chick flick with a great soundtrack'.
The snippet is a man n woman talking in a foreign language (not sure if it could be italian/spanish/portugese)
I have only heard the snippet once.
The word 'si' was used which i think could be in all 3 languages.
I have only watched this film once plus it was on tv late n I fell asleep, so have no idea!
I can win 10 cinema tickets for our local odeon if i can get it right.
Thats 2 cinema trips for me and my 4 kids.
Cheers.
