I pre-ordered my copy of her album from Play.com - it was the signed sleeve-case version. It got dispatched yesterday and arrived today. Authentic signiture, some of my followers on Twitter have this too and we compared. You can also tell with the pen marks - play.com are always genuine.
SO HAPPY WITH THIS! Release is not until Monday as well
