pulled out all the stops for a lavish 37th birthday party at New York City hotspot Avenue on Friday.
Surrounded by a bevy of Victoria's Secret models, pals Russell Simmons and Bradley Cooper
and his mother Irmelin, the birthday boy "was having a great time and talked to everyone at the party," says a source.
The actor also spent the evening surrounded by Brazilian supermodels, including Alessandra Ambrosio, Izabel Goulart and Ana Beatriz Barros.
"It was a very exclusive crowd," adds the source, confirming that DiCaprio rented out the entire club.
At the party, which raised $1.3 million for DiCaprio's various wildlife protection projects and disaster relief for Haiti, guests drank Cristal champagne – including a couple of vintage bottles at $50,000 a pop.
Adds a second source: "It was a crazy party."
