In the fourth episode, after an argument with a participant regarding the purchasing of shampoo at the request of one of the other woman Frédérique, Benattia uttered the words to the camera that led to the establishment of her celebrity status:
Nabilla's uttering created a media buzz in France and generated many parodies, on the internet and in various media. La Grosse Équipe, the production company behind les Anges, registered four trademarks in mid-March with l'Institut national de la propriété industrielle, the French intellectual property registry. These were "Allô, quoi", "Allô, t'es une fille, t'as pas de shampooing, c'est comme si je dis, t'es une fille, t'as pas de cheveux", "Allô, non mais allô quoi", and "Allô, Nabilla la vraie vie de la famille Benattia". The last of these resulted in rumours discussed on Twitter that a new reality show was in the offing with her as the star. In a TV interview on the talkshow Grand journal, watched by 1.8 million viewers, Benattia confirmed that there will be a reality TV show following her day-to-day. La Gross Équipe has also registered "Nabilla cherche l'amour" as a title for a TV show.
