Leonardo DiCaprio turned 48 this week -- and anyone who's anyone swung by to party.
The A-lister threw a massive bash Friday to celebrate his birthday at a private mansion in Beverly Hills, where a lot of famous faces were seen coming and going throughout the night. Truly, it was a classic who's-who of Hollywood ... something only a select few can pull off.
Among the high-profile guests ... LeBron James, Bradley Cooper, Sir Mick Jagger, Tobey Maguire, Adrien Brody, Jamie Foxx, Rami Malek, Casey Affleck, Wesley Snipes, Stella Maxwell, Nicky Hilton, Sommer Ray, Jennifer Meyer, Caylee Cowan and many, many more.
