"What Other People Say" is a song by Australian singer-songwriter Sam Fischer and American singer Demi Lovato.

It was released on 4 February 2021 by RCA and Island Records on digital download and streaming formats as the second single from Lovato's seventh studio album Dancing with the Devil... the Art of Starting Over and Fischer's debut studio album I Love You, Please Don't Hate Me.

[3] Fischer said he was "blown away" when Lovato agreed to sing on the track with him, and added that the song is "a confession, realizing how far away you can get from who you are in an effort to be liked.

It's why I wanted to make this song with Sam – ultimately it's about two humans coming together to connect and find solutions to their problems".

[7] Danielle Pascual from Billboard ranked the song as one of Lovato's best collaborations in her entire discography, describing it as a "powerful emotional ballad" that "showcases her varied range while giving Fischer room to soar".
