Marilyn Monroe (/ˈmærəlɪn mʌnˈroʊ/; born Norma Jeane Mortenson; June 1, 1926 – August 4, 1962) was an American actress, model and singer.

Did Marilyn Monroe sing any songs?

Marilyn did all her own singing – every single word. There was never any question about 'dubbing' her voice. She wouldn't have allowed it since it was unnecessary, and to her, it would have been a cop out. Another example of how hard she worked was when we were making Gentlemen Prefer Blondes.

Did Marilyn Monroe have a good singing voice?

Did Marilyn Monroe have a good singing voice? On the sidelines but not out loud and not a good choice. (The high notes of Diamonds Are a Girls Best Friend are said to have taken her name from her.) Indeed, Marilyn Monroe always sang somehow, her acting voice was an artificial voice and played very carefully.
