On the 1960s sitcom, Eden played a 2,000-year-old genie who falls in love and eventually marries a handsome astronaut – played by actor Larry Hagman, who becomes her master.
Once on stage, Eden turned to the audience and gave her signature head nod and wink, bringing out her new "master" – former President Bill Clinton.
The 42nd president, who has been an outspoken proponent for AIDS and HIV research, then emerged from offstage to join Eden, who was also accompanied by Olympic swimmer Greg Louganis and pop-singer Fergie.
After thanking the ball's organizers, Clinton encouraged others to be more involved with the anti-AIDS efforts
, saying those who wish to help don't "have to be scientists, they do not have to be doctors, they have to be people who care," the New York Daily News notes.
In addition to Clinton's appearance, Elton John delivered a speech that captivated the audience according to Marie Claire magazine, and singer Adam Lambert performed.
Actresses Hilary Swank and Carmen Electra were also in attendance as well as fashion critic Kelly Osbourne – daughter of English heavy metal singer Ozzy Osbourne.
