The New York Post is reporting that Jay-Z and Beyoncé will get married during Jay’s “surprise” 37th birthday party this weekend. “Beyoncé is throwing Jay a four-day birthday party, but it’s really a wedding,” said one source. Guests, including family and close friends, were told to have passport applications filed by last Friday so they can attend the bash on a yacht in St. Barts. But insiders said the guests will also be ferried over to Anguilla for the wedding at Cap Juluca, a five-star resort. Another spy said Beyoncé and Jay had toured the site earlier this year and approved it for their nuptials.
