Lottie Collins (16 August 1865 – 1 May 1910) was an English singer and dancer, most famous for introducing the song "Ta-ra-ra Boom-de-ay!"

She would sing the first verse demurely and then launch into the chorus and an uninhibited and exhausting skirt dance with high kicks (especially on the word "BOOM") that exposed her stockings held up by sparkling garters, and bare thighs.

[13] She returned to America in September 1892 to perform "Ta-ra-ra-Boom-de-ay" as an entr'acte at the Standard Theatre, New York, but received a bad review from the critic of The New York Times, who described her as 'a mature woman', referred to her as 'Charlotte Collins' and mentioned she had been detained in quarantine when arriving 'on an infected ship'.

[14] Another of Collins's dance sketches in the 1890s was The Little Widow, and she also had a hit with the song Daddy Wouldn't Buy Me A Bow-wow.

In 1898, she apparently attempted suicide by cutting her wrists and neck with a penknife,[9] but her wounds were minor and she was discharged from hospital the same day.
