On April 3, celebs flocked to the infamous Playboy Mansion on Los Angeles for the premiere of Amazon Prime Video’s upcoming docuseries "American Playboy: The Hugh Hefner Story."

Guests, including Orlando Bloom, Jared Leto, Brett Ratner and Kendra Wilkinson-Baskett, enjoyed specialty cocktails provided by Hilhaven Lodge such as the “Mr. Playboy” and “The Centerfold” and enjoyed music spun by DJ Myles Hendrik.

Other famous faces at the mansion included Boris Kodjoe, Miguel, Diego Boneta, Lindsey Pelas, Lola Kirke, Natalie Morales, Beau Mirchoff, Jax Taylor, Sheana Marie, Nolan Funk, Kurtwood Smith and Taryn Manning.

Head of Unscripted for Amazon Originals Conrad Riggs, COO of Amazon Studios Albert Cheng, Chief Creative Officer ofPlayboy Enterprises Cooper Hefner and series executive producers Stephen David, Peter Jaysen, and Dick Rosenzweig were also on hand.

"American Playboy" is the authorized story of Hugh Hefner, who set out to disrupt the status quo and created one of the most recognizable brands in history. The docuseries combines archival footage, pulling from thousands of hours from Hefner’s personal archives, and interviews with notable figures including Jesse Jackson, Gene Simmons and Bill Maher.

Produced by the Emmy Award-winning Stephen David Entertainment and Alta Loma Entertainment, "American Playboy" begins in post-war America and takes us through the launch of Playboy magazine in 1953 and the next six decades of Hefner’s life and career.

As he built his empire, Hefner became both a social justice advocate and a target of the conservative movement while becoming an outspoken defender of civil rights, freedom of speech, gay rights and, of course, sexual freedom. The series is the result of unprecedented access to thousands of hours of never-before-seen footage from both Hefner’s and the Playboy archives and Hefner’s personal scrapbooks, which number more than 2,900 and constitute a Guinness World Record.

Hefner, who celebrated his 91st birthday on April 9, has been deeply involved in the development and production of "American Playboy." The series premiered on April 7 on Amazon Prime Video.
