Serious answer...
Cheryl's presence (and the way attention was drawn to her) probably didn't help Kimberley much.
There has been a perception that she is safe from the start, having the Girls Aloud fanbase behind her, then highlighting that she is best friends with one of Britain's best known celebrities made her seem even safer.
The dance-off is making the votes a lot more erratic - people are voting for the people they think are at risk (Fern last week, Richard this week) and the ones that don't seem to be at risk aren't getting as much attention, so it seems.
Kimberley will be fine next week - her fans will vote to protect her and being in the dance-off will give her another "storyline" - which she desperately needs, as her personality is not shining out at the moment (hence the bot tag).
