Unless you live under a rock you probably know about the upcoming Royal Wedding.  I personally have no plans to wake up at 4 AM (which is the time I’d have to turn the TV on to catch the wedding live) but I know there are literally millions of people who do.  Disney Publishing wants fans of the Disney Princesses to get in on the Royal Wedding fun too and they’ve updated one of their popular iOS applications to do so.  The Disney Princess Dress-Up:  My Sticker Book is a universal (iPhone, iPod Touch and iPad) app which allows users to dress up their favorite Princess with a variety of clothes and accessories.  Children can use their own photos too to create their own Princess portraits and then email them to friends and family members right from the app.  The latest update to the app adds on a new Princess (Tiana from The Princess and the Frog) along with 7 new stories and 25 new outfits and accessories.  The My Sticker Book is available for download for $3.99 via the iTunes App Store here.
