Diana Ross' 75th Birthday Party Brought out Leonardo Dicaprio, Khloé Kardashian & Many Other Celebs

Leonardo Di Caprio, the Kardashians, Diddy and many others joined Diana Ross on stage as she performed her greatest hits during her 75th birthday concert party.

Singing legend Diana Ross celebrated her 75th birthday with a lavish bash. The star-studded affair started at the Warwick night club and culminated at the Hollywood Palladium where she treated her well-wishers to a special concert.

Diana arrived at her concert venue in a Rolls Royce convertible. She looked stunning in a fluffy vintage orange gown as she walked directly to the stage from her car.

Spotted in the extravagant fete were Leonardo Di Caprio, the Kardashians, Khloe and Kourtney with their mother Kris Jenner, P. Diddy, and Beyonce who serenaded her with the birthday song.

Stevie Wonder was also there to sing her a happy birthday as well as Robin Thicke who sang, “Endless Love” with her.

Diana invited her guests to join her on stage throughout her five-costume-change performance. Diddy and his three daughters, D’Lila Star, Jessie James, and Chance took the stage when she performed “Stop! In the Name of Love.” She also sang “Love Hangover” with her son, Evan Ross and his wife Ashley Simpson. Towards the end of the night, Kourtney and Khloe danced to “Take Me Higher” on stage along with their mother Kris, Evan and his sister Tracee Ellis Ross.

DJ Khaled provided music after the show and mashed up his song “All I Do Is Win” with Diana’s classic, “I Will Survive.”

Sometime during the night, a reluctant Leonardi Di Caprio in a black hoodie was pulled to the stage along with his mother. The Oscar winner said a quick “Happy Birthday to the legend, Diana Ross” before exiting the stage leaving his mother who gave a hug to the birthday girl.

Diana’s epic birthday celebration doesn’t end there. On March 28, her concert film, “Diana Ross: Her Life, Love and Legacy” hits theaters for a one-night only screening. The film will feature rare footage of the icon’s 1983 Central Park concert. In June, Diana will also commence performances at the Wynn Las Vegas for her "Diamond Diana" concert series.
