There is no real evidence that it will be Sheila. She made a comment on her my space that she "could be" going on BB. However, if she was the mystery housemate, they would not allow her to say that.

There is some evidence that it might be a guy named Brian from a previous season (I forget which). When the list of housemates was first put up, the "unknown" housemate had a folder named Brian in the html code for the page. The folder was later renamed to unknown.

I think it would be weird if they took a UK person to the US house because the formats of the shows are SO different.
