I find her excruciating. My daughter quickly grabs the remote and fast forwards the ads so I don't have to listen to her butcher one of my favourite songs.
The trouble is, they're the sponsored ad, so you have to time it just right so that you don't hear her annoying voice just before the programme starts. First world problems, eh? ;)
It's a very successful ad - the number of threads about "who's singing?" alone prove how much it gets noticed - plus I would really like that red dress
:-)
