Miley Cyrus raised $69,000 for AIDS research when she auctioned three customised 'Vanity Fair' covers of Caitlyn Jenner.

The 22-year-old singer was being honoured at the amfAR Inspiration Gala at Spring Studios, in New York, on Tuesday night (16.06.15) with the Inspiration Award alongside Andy Cohen because of her work to increase the social acceptance of transgender people.

Miley used the occasion to present her bespoke 'Caityln Collection' bejewelled paintings for sale to raise much needed funds in the fight against the disease.

Her bedazzling artworks were inspired by Caityln Jenner's recent Vanity Fair cover, which announced her new identity to the world following her gender transition from ex-Olympian Bruce Jenner.

The three creations fetched a bid of $65,000 but that figure wasn't enough for Miley and she grabbed the microphone from the auctioneer and offered to clean the winning bidder's house while naked for more money.

The pop star - who posted a snap of her creations in progress on Instagram last week - yelled: ''My left boob is bigger than the right - I'll show you! What about $69,000? I'll clean your house ... naked!''

Her offer worked and the final sale price was the figure she asked for.

Meanwhile, Miley was moved to tears on the night and received a standing ovation after accepting her prize.

Thanking her parents, Billy Ray and Tish, during her 11-minute acceptance speech, she said: ''I'm happy to have you here and I just want to tell you how much I love you. I hope this makes you proud and somehow makes up for all the sh*t that I do all the time. You are two of the most selfless people and you 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 learn that. People say they don't choose their family, I chose my family every time.''

The star is a vocal supporter of the LGBT community and the 'Caitlyn Collection' is part of her Dirty Hippie line of neon-toned, bedazzled accessories and visual arts. Miley also launched an Instagram series called #InstaPride to celebrate transgender people.

The money raised from the sale of the art will be used for HIV and AIDS research.
