Sophie is pregnant, and the bump is already noticeable. So filming a sexy video is out of the question. I think what she should do is concentrate on how good her face looks on screen. Tons of make up, lot of hairstyles, and lot of gown type dresses which hide the bump. Something like the Take Me Home video, only with a whole lot of Sophia Lauren style...
Here's a collage of most of Sophia Lauren's hairstyles, i think Sophie should do this.
Also the music video would be the perfect place for product placement for Rimmel and Monsoon. I think she should get the camera to focus on her highlights - eyes, lips, curves etc., and wearing make up... oh and even maybe a shower scene again!! I don't know if the video will have any sex appeal at all, compared to the recent videos that have been coming out (Rihanna, Britney and hell, even Hilary!)
I think Sophie must break her sophisticated look for this video, and do a bit of skin show... Afterall, its a song about comparing herself to Sophia Lauren... c'mon Sophie... the video should ooze sex appeal!
