Jay-Z refused to spare any expense for his 40th birthday celebrations.

The rapper and wife Beyonce Knowles flew their closest friends -including Oprah Winfrey, Kanye West, Alicia Keys, Mary J Blige, Kate Hudson and Ne-Yo -out to the Dominican Republic, paying for their private jet travel and luxury suites themselves.

The bash, held last Friday (04.12.09), had a ‘Scarface’ theme, with the venue decked out like the home of Tony Montana, and partygoers were treated to Dom Perignon champagne and caviar.

The hosting couple’s parents were the guests of honor at the party, which was held in a villa at the resort of Casa de Campo.

However, the rapper -real name Shawn Carter – made sure he continued to be the centre of attention, performing his hit ‘Empire State of Mind’ with Alicia Keys and P. Diddy.

Following a touching video display of messages from his friends, Jay-z saw the evening come to a climax with a big fireworks display at midnight, with synchronized swimmers dancing alongside in the villa’s pool.

The following day, guests were treated to a brunch barbecue -with Beyonce showing off her culinary skills behind the grill, before a group of revellers took to the seas on a private yacht.
