Not at all. Her looks are very boring to me. You could pull any average girl out of HS and make her look nice like Ariana with the right hair and makeup team, though I think there's something weirdly fake about her looks that actually turns me off.
Taylor and Katy come to mind for pretty pop girls since Rihanna. Though Rihanna is still easily the most beautiful in awhile.
I have to admit that she looks quite good here though:
Maybe this image would work better for me. There's something about the shape of her face and her eyes that seems totally lifeless and cold to me, and I think having her hair back in that damned ponytail exacerbates it.
