It was released on 2 September 2022 through Warner Music Italy as the lead single from her eighth studio album E poi siamo finiti nel vortice.

[3] Annalisa explained the meaning of the song:[4]I wrote "Bellissima" in August 2021, at a decisive moment in my career, the one when you look in the mirror and decide that once you have cleared all filters you can finally build something completely new.

[7] Niccolò Dainelli of Il Mattino also noted a "discographic rebirth" of the singer with "Bellissima", dwelling on the fact that the project presents itself "as a dance at once sexy and desperate, where she tells of the end of a love story and the subsequent pain she felt".

[10] Filippo Ferrari of Rolling Stone Italia, reflecting on the singer's career, wrote that with "Bellissima" and "Mon amour" Annalisa has "finally entered her golden era; ... with her launch into the world of pop without too many meanings or pretensions other than to get into your head" and that "she really started to rock when she decided to throw herself in a bit".

Ferrari pointed out that compared to the Italian music scene, the singer has undertaken the "lightness' similar to Paola e Chiara or Elodie, appreciating "the energy of thinking it, after [Annalisa's] 35 years of age".
