Leonardo DiCaprio Celebrates 50th Birthday With Brad Pitt and His Girlfriend Ines De Ramon, Paris Hilton, Cara Delevingne and Robert De Niro

Leonardo DiCaprio turned 50 on November 11. In honor of the anniversary, the actor threw a grand party at a private residence in Los Angeles, where he gathered his parents and colleagues from the film industry, close friends and models.

The event was held behind closed doors, but the paparazzi managed to take a few photos of the celebrity guests outside the house. Among the guests were: Brad Pitt, who arrived in a grey Porsche with his girlfriend Ines de Ramon, Paris Hilton, who was captured by photographers in a sparkly dress and a personalized glass, as well as Robert De Niro, Cara Delevingne, Katy Perry and Orlando Bloom, Jamie Foxx, rappers Dr. Dre and Tyga, Mark Ruffalo, Edward Norton, Sara Sampaio and many others.

Director Steven Spielberg arrived with his wife Kate Capshaw, and the actor's 81-year-old father with his stepmother Peggy Farrar. Leo's mother, of course, was also invited. She arrived with her husband David Ward.

DiCaprio's close friend Tobey Maguire and beloved Vittoria Ceretti sang along with 74-year-old Stevie Wonder, who became the star of the evening and performed the song Happy Birthday for the actor. According to insiders, during the song the Titanic star smiled shyly, and 26-year-old Vittoria kissed him on the cheek. DiCaprio's co-star in the film, Kate Winslet, was also among the guests.

Last year, Leonardo DiCaprio's party was attended by Kim Kardashian, Rita Ora, Beyoncé, Kate Beckinsale and many others.
