The proofers also forgot to mention the slight white scar looking bump on her chin. Which is also in the video. So matched up moles, birthmarks, and a small round scar on the chin. No girl is going to go through the effort in faking a video using makeup. There would be no point.
I'm inclined to believe it's her for the simple fact that she was smart enough not to say a single word. Which is also odd for non-famous girls to do. Normally it's "I miss you," "I want you to fuck me daddy" or w/e else chicks say when recording videos for their boyfriends. This had nothing. Which means said girl in the video knew people would recognize the obviously famous British voice and said nothing.
Her camp releasing a statement saying nothing was nude means literally nothing. 0%. All the other pics had her face in it, the video did not. So to avoid her being identified as the girl in the video they said that knowing her face wasn't in it, giving her plausible deniability. Victoria Justice claimed her nude leaks wasn't of her. Turns out she was lying and it WAS her.
