P. Diddy spent $3 million on his 40th birthday party.

The hip-hop star celebrated the landmark day with Jay-Z, Bono, Nelly and Denzel Washington at the Garden of Eden-themed bash held at New York's Plaza Hotel last Thursday (19.11.09).

P. Diddy - real name Sean Combs - had invited 500 people to celebrate with him and treated them to gallons of champagne and Ciroc vodka - which is his own brand of the spirit - and a silver confetti drop.

There was also a private performance from the American gospel singer Al Green.

P. Diddy - who is one of the richest hip-hop stars with an estimated net worth of $346 million - decorated the venue with a $30,000 orchid display, a black dance floor and a black chandelier.

A source said: "He really pushed the boat out for this one - and then some. It was an amazing party and Diddy was on great form."
