"Sei bellissima" is an Italian song written by Claudio Daiano and Gian Pietro Felisatti and performed by Loredana Bertè.

During the years Bertè claimed to be the actual composer of the song, but that at the time she was unable to sign it as she was not a member of SIAE.

[1] The musical arrangement by Vince Tempera was inspired by Riccardo Cocciante's "Bella senz'anima".

[3] The song was the first hit for Bertè, following the commercial failure of her debut album Striking.

[2] The verse "a letto mi diceva sempre non vali che un po' più di niente" (i.e. "in bed he used to say 'you are not worth a bit more than anything'") was initially censored and replaced by "e poi mi diceva sempre non vali che un po' più di niente" ("and then he used to say 'you are not worth a bit more than anything'").
