It did get rounder/fuller, her face, for sure, noone can deny that. But photoshop, light, angle, all can add up to it as I said. Its not just that but it may additionally make her look like that. Oh yeah, I miss that bone structure too but honestly she did have a kind of rounder face even in earlier years so its not big surprise that with 'age' ( sounds funny..shes still damn young but whatever) it will change a bit aka 'mature'...
And in that LOreal ad its not that roundenss of the face that is weird, its just whole picture is weird.
Either way, shes lovely and is always in my heart <3
