Sadly, Duffy decided to wait until everyone had seen the eye-poking terror of her 'bicycling off to get some Diet Coke with a look of terror on my face' advert. If only she'd decided that doing adverts wasn't really her before, eh?
"I have only got 100 per cent to give and all of that goes towards being creative, so I can't really open the doors to all the other things.
"I have so many desires creatively, but I have to tread carefully that I also don't sell myself out personally.
"What you see with me is what you get. I just put my whole energy into the creative side."
Presumably, the lack of even the most stubborn stain of creativity in that Diet Coke ad means that she didn't feel it would eat into that 100%.
