Last week, as you may well recall, we played a little game of 'Whose back is this?'

The answer, as most of you managed to work out, was Dale Howard from BB9. We're guessing you've seen quite enough of his back by now, so for variety's sake here's a nice picture of his front.

Right. New week, new challenge. This time we're getting cheeky and asking you to guess the owner of this pert and perky celebrity rump.

Just use the space below to make your guess and we'll reveal the answer this time next week. There's absolutely no need to rush though - feel free to spend as much time as you like "formulating your thoughts".
