Despite all the other lies she spouts, I do actually think she is around 5'9 possibly 10. In the sidemen tinder video which she is part of, they talk a lot about height and some of the guys who are known to be around 5'7 etc are shorter than her.
Her segment starts around 12 minutes.
The hilarity is though, she says "why is everyone talking about my height, I'm not that tall"... she mentions it in her own videos every moment she gets!
Maybe they lie about their height too here’s three photos of her with people who are 5ft 7, 5ft 10 and 6ft 1. She looks slightly taller than talia who’s 5ft 7, smaller than james when she’s heels who’s 5ft 10, and considerably shorter than Calfreezy in heels who’s 6ft 1. I remember on a live someone asked how much taller james was and she said 3 or 4 inches as well as saying he was 5ft 10. Also you can see the difference between Selena and Taylor is much bigger than Selena and Emily. And Taylor’s actually 5ft 10
