She's tweeting away exciting details about her Big Day (Regis Philbin is attending!) and we want to help her celebrate. At noon today, check out our Twitter page for a special message. Be the first person to re-Tweet it and you'll take home one of these gorgeous stackable rings by Ivanka Trump Fine Jewelry. "I have given these as birthday presents," said Trump.
