I'm sure we all have.....but to go from being extremely vocal,pious and scathing is another matter surely. She is hardly struggling to keep the wolf from the door, so if true is a sell out of what she said she was all about borne out of pure greed.
Personally any celeb who does advertising come across as desperate and greedy. She is over exposed already, to her fans great but to those in the middle it could be a total turn-off.
Not necessarily. Kate Bush (who has integrity pouring through her veins) did an advert for Japanese watches in the early days but she looked so utterly gorgeous in it I'm very glad she did.
