Alex Rodriguez and Kate Hudson jetted to the Dominican Republic the other day for this weekend’s David Ortiz Celebrity Golf Classic. While they’re there, the lovebirds are slated to hit Jay-Z‘s big 40th birthday bash at the nearby Casa de Campo resort. Spies report Jay-Z and his multi-Grammy nominated wife, Beyoncé, arrived yesterday for the festivities. Other guests expected at the party at a plush villa include Sean “Diddy” Combs and Oprah Winfrey.
