Miley Cyrus was moved to tears at the amfAR Inspiration Gala New York on Tuesday – and she also moved a lot of people to donate to the AIDS research organization.

Before being honored with the foundation’s Inspiration Award alongside Bravo star Andy Cohen, the pop star helped bring in some major donations by offering some of her very own artwork for auction.

Rocking a fiery red, heart-decorated gown (and some armpit hair!), Cyrus, 22, unveiled the Caitlyn Collection as part of her Dirty Hippie line of neon-toned, bedazzled accessories and visual arts. (She showed her first eccentric collection at designer pal Jeremy Scott’s New York Fashion Week show in the fall.)

The Caitlyn Collection was inspired by Cailtyn Jenner, who recently introduced her post-transition self in the new issue of Vanity Fair. Cyrus’ artwork – three framed, bedazzled and signed copies of the Jenner VF cover – reached a bid of $65,000. But the “Wrecking Ball” singer took matters into her own hands when she grabbed the mic from the auctioneer to beckon even more bids.

“My left boob is bigger than the right – I’ll show you!” Cyrus told the crowd at Spring Studios, quipping, “What about $69,000? I’ll clean your house naked!”

Sure enough, the singer-songwriter’s Jenner pieces sold for $69,000.

But, when it was time for Cyrus to take the stage to accept her award, she kept it serious, thanking her heroes (including amfAR founder Elizabeth Taylor and longtime amfAR advocate Sharon Stone) and speaking about her new Happy Hippie Foundation, which aims to help homeless and LGBT youth.

“There are so many people around the world that deserve this recognition,” said Cyrus. “They’ve dedicated their lives to finding a cure for those living with HIV and AIDS, and they’ve used their voices to speak out against the brutal and unfair condemnation and the abominable stigma that comes with this disease. And by receiving this award tonight, I promise to continue to fight along for a cure for this epidemic.”

The former child star got particularly emotional when addressing her parents, Billy Ray and Tish, whom she brought along to celebrate at the event, which was produced by Josh Wood.

“I just wanna tell you how much I love you, and I’m gonna f—ing cry like a loser,” said Cyrus, visibly tearing up. “I just wanna tell my parents that I hope that this makes them proud and somehow makes up for all the s–t that I do, all the time.

“You are two of the most selfless people, and you have taught me and all my siblings how important it is to be there for those who need us and how important it is to care about other people and their lives. So thank you for making me like that.”

Wrapping up her impassioned acceptance speech, the singer got even more choked up, telling the crowd:

“If I know anything after doing this for however [long] that I’ve been doing this, nothin’ means s– except f—in’ helping people,” she said. “That’s the only thing that makes us feel like we really accomplish anything at all. I hope one day that I’m here on earth to experience an AIDS-free world.”
