Miley Cyrus attended the recent AmfAR gala and turned many heads with her unusual and provocative dress. However, she also went ahead and submitted a massive donation, which caught a lot of attention as well.

Cyrus left little to the imagination with a provocative, "barely there" black Tom Ford dress during the event with a sheer top and sequined crisscrossed straps.

While there was a lot of money donated during the AmfAR gala, what particularly caught the attention of the attendees was Miley Cyrus' whopping $500,000 donation.

The Foundation for AIDS Reserch (amFAR) event was made in honor of fashion designer Tom Ford, as a way to raise funds for HIV/AIDS research.

In what seemed like a "competitive Hollywood sporting event," the "Wrecking Ball" singer reportedly bought a Ryan McGinley photo of a naked woman for $300,000, while fellow Viva Glam MAC Cosmetic endorser Rihanna bought a pair of Harry Winston earrings for $35,000.

Aside from the initial donation through the live auction, Cyrus gave another $200,000 to the charity, while Ford and Rihanna donated $100,000 each.

"The Viva Glam girls know how to roll," said John Demsey, MAC AIDS Fund Group President.

"I'm a little drunk, that's why I'm half a million deep," shared Cyrus on Wall Street Journal.

"I do this sort of thing sometimes. I like to start things up, to get it along, to get people excited," the singer explained.

In a more serious tone, Cyrus explained the reason behind the huge donation.

"If I'm going to have a voice I would like to start an open dialogue about prevention and awareness and how people in the world have been affected by HIV and AIDS," the 21-year old singer said in an interview with NY Daily News.

"I could break down people's walls that have been built up around sexuality," she added.
