Turning 40 is a milestone, and to hip-hop mogul Diddy, it's one to splurge on.

The Bad Boy Entertainment boss recently threw himself a lavish 40th birthday party in New York, spending a whopping $3 million on the bash, reports Page Six.

Some of that money was spent on things like his Garden of Eden theme, which included a $30,000 orchid display, a specially installed black dance floor and black chandelier, a silver confetti drop, and a performance by Al Green.

You know when Diddy throws a party, celebs come to support. The all-star guest list included Bono, Jay-Z, Martha Stewart, Denzel Washington, Nelly, and Fabolous.

The security was tight too, so tight "Twilight" star Kellan Lutz was barely able to get into the VIP area.

All this went down at The Plaza Hotel in New York City.

Now that's BALLERSTATUS! Happy birthday Diddy!
