Singer Meghan Trainor on Tuesday had her newest music video taken down and re-uploaded upon discovering that the original had been manipulated to make her look more slender than she is.

After the “Me Too” video, directed by Hannah Lux Davis, went up on the video-hosting service Vevo on Monday, Trainor fans noticed that the singer — whose signature tune “All About That Bass” celebrates bodies not necessarily conforming to rigid standards of beauty — looked more svelte than normally. One fan Monday morning tweeted, “The people who edited the Me Too video photoshopped Meghan Trainor.”

Within the hour, Grammy Award-winning Best New Artist Trainor, 22, posted a Snapchat video declaring, “Hey guys, I took down the ‘Me Too’ video because they Photoshopped the crap outta me, and I’m so sick of it, and I’m over it…. I told them fix it. My waist is not that teeny. I had a bomb waist that night [of the shoot]. I don’t know why they didn’t like my waist. But I didn’t approve that video and it went out to the world. So I’m embarrassed. I told them to fix it ASAP…. I’m sorry about this.”

On Tuesday, the unaltered version was posted online, with Trainor writing on Instagram, “The real Me Too video is finally up! Missed that bass. Thank you everyone for the support.” Accompanying the message were before-and-after images of herself in the video, seen from behind, dancing in a short, blue, spangled dress, the differences clearly visible.

Representatives for director Davis and for Trainor’s record label, Epic, did not respond to Newsday requests for comment.

Trainor had told USA Today that she initially thought the slender images she was seeing online was the work of fans “and was like, ‘Why are fans ruining my waist? Are you kidding?’ Then I went to the video and was like, ‘Oh my god.’ I texted the editors, like, ‘I never asked you to touch my waist. I want my waist back.’ ”
