Beyonce pulled out all the stops for her husband Jay-Z‘s 40th birthday party at Casa de Campo in the Dominican Republic. The 60-odd guests at the ’20s-themed fete included Kanye West and girlfriend Amber Rose, Sean Combs and girlfriend Kim Porter, Alex Rodriguez and Kate Hudson, Swizz Beatz and Alicia Keys, Warner Music chief Lyor Cohen and designer Tory Burch, plus DJ Cassidy, who spun for the party. “Diddy gave a toast,” says our insider. “Jay-Z’s friends also put together a video saying how much they love him.” The festivities, which featured synchronized swimmers, fireworks and an impromptu performance of “Empire State of Mind” by Jay-Z and Keys, lasted until 5 a.m. The next day, our source said, Beyoncé presided over a surf-and-turf brunch for guests at the luxury villa where she and Jay-Z were staying.
