loved the pilot! NEED song help tho!

Okay, there's a funny scene where a tipsy Joan Cusack is sipping on a cocktail while in the bedroom closet, cutting holes with scissors in all her ex-husband's shirts, and she's listening to this song with French lyrics... it's a very popular song, I recognized the tune immediately.. However, because it's French, I have no idea how to begin looking for it! Lol

any help would be awesome, thanks.
