The actor turned a year older on November 11 and his birthday celebrations took place in New York, reported TMZ Online.
The venue, which crammed in 100 of his closest friends and family, was at the TAO Downtown in NY, and in the process DiCaprio raised millions of dollars for his foundation, according to TMZ Online.
2-Chainz performed his own version of 'Happy Birthday' as well as inviting "brother Leo" up onstage for a speech. West followed with a performance fit for his 'Yeezus' concert, as he played 'Good Life', 'Gold Digger' and many more.
West's fiance, Kim Kardashian, was also at the venue to support her man as she shared a video of the performance.
The celebrations reportedly didn't end until 4am and the actor was spotted having a good time with his new girlfriend Toni Garrn.
The birthday bash is said to have raised USD 3 million for the 'Leonardo DiCaprio Foundation', an organisation focusing on efforts to create peace between humanity and the natural world.
