Are Beyonce and Jay-Z planning to wed this weekend? The powerhouse duo and some record industry execs were overheard talking about a four-day surprise 37th "birthday" party for Jay-Z but insiders say there may be wedding bells at the event. "Beyonce is throwing Jay a four-day birthday party, but it's really a wedding," said a source. Guests were reportedly told to get their passports in gear for the event, which will take place on a yacht in St. Barts, and insiders say the party boat will make a pitstop at a five-star resort in Anguilla for a wedding ceremony. Reps for the couple have not commented.
