Well, naz, if you input "kellogg's special k" and "red swim suit" into the yahoo search engine, all you get is a whole load of hits saying she is Lisa.
If she's someone else...who is she??
She doesn't look anything like Lisa Snowdon. Just because we don't know who it is, that doesn't mean we can't know who it isn't. Er...if you see what I mean.
Lisa Snowdon has advertised Special K in the past, but this isn't her.
