I get nothing on this person.
I mirrored it and searched and it brought a lot of images of " Ally Breelsen" aka Angelina Doreshkenova but, I don't think it is she.
ALTHOUGH , ..... she did have several images of herself wearing Mouse ears and other stuff on her head like the horns were on the image your searching.
Take a look .
Oh, and is the only image you have of this person and do you have any more info on her ??
