Beyonce Knowles reportedly splashed out on a $3 million three-day birthday party for her rapper boyfriend Jay-z earlier this week. Following the New York premiere of her new movie Dreamgirls, Knowles whisked Jay-Z - who turned 37 on Monday - to an airport where she had chartered two planes to fly 20 of their closest friends to the island of St Martin in the Caribbean.

According to the New York Daily News, the guests, who included Knowles' former Destiny's Child colleague Kelly Rowland, spent the next two days aboard a 270 foot long yacht consuming lobster and champagne. They also reportedly had two helicopters at their disposal. An insider tells the publication, "The party must have cost $1 million a day." On Thursday, Jay-Z - real name Shawn Carter - was in Miami, Florida and he is expected to be back in New York this weekend, and not getting married to Knowles on the Caribbean island of Anguilla as widely reported.
