Why? Are they not exactly the same as the clip after that? I firmly believe its her.
People dont know how much of a difference lighting, makeup can do. And bodies fluctuate from time to time as well. Stop trying to find flaws in her content every time and just enjoy it, she is unreal. Last time there were some great content from her, the boobs looked too big and her nose looked off to some people, lol.
And we know there no reason for Sydney not to show off like this.
Unless its proven otherwise, its her to me.
