Over more than two decades, Elton John has turned his annual Oscars viewing party into the place to be not only during the awards telecast, but also after all the trophies have been handed out. And that's all very good news in the fight against AIDS.

The event, now in its 22nd year, raised an estimated $5.1M last night for the Elton John AIDS Foundation. Since 1992, the singer's organization has collected more than $200M to support HIV/AIDS programs in fifty-five countries.

Celebrities in attendance included Lady Gaga, Britney Spears, Heidi Klum, Quincy Jones, Whoopi Goldberg, Steven Tyler, Neil Patrick Harris, and many more. Owing to the successful fundraiser was the inclusion of several once-in-a-lifetime auctions - including five nights in Tyler's Hawaiian getaway ($100,000) and a signed piano used by Elton John during the party ($220,000).

"Twenty years, 20 years since this disease came to the attention of people in this country," Elton said during the event in 2012. "We have the tools for a cure, but the enemies of a cure are bigotry, stigma and greed."
