Caitlyn Jenner Vanity Fair cover: Miley Cyrus raises £55k for Aids charity by auctioning customised editions

Miley Cyrus is doing her part in the fight against Aids and HIV by raising tens of thousands of dollars towards helping eradicate the disease.

The Disney star-turned-twerking queen raised £55,000 ($86,000) for the AmfAR charity by auctioning off autographed copies of Caitlyn Jenner's iconic Vanity Fair cover.

Guests at the charity gala, held in New York, were stunned when the pop star unveiled three front pages which she had customised. The donated covers are also the first time the former Olympic athlete-turned-reality star had publicly written her autograph as Caitlyn.

"Tonight @MileyCyrus donated one of her latest artistic pieces featuring and signed by @CaitlynJenner – the first available autograph from Caitlyn herself. These special pieces were auctioned tonight with proceeds supporting our HIV/Aids cure research. #CallMeCaitlyn #amfARInspiration."

Cyrus's night ended on a high after she was awarded the Inspiration Award by Kenneth Cole.

"I just hope this makes my parents proud and somehow makes up for all of the s*** that I did," she said during her acceptance speech.

And Cyrus's philanthropic efforts don't stop there. The keen LGBT rights recently launched her online campaign for gender non-conforming, using the hashtag #instapride. The project, which is a collaboration between her non-profit organisation Happy Hippie and social networking site Instagram, aims to provide a platform for transgender people, as well as those who support them.

Speaking to Time magazine, the 22-year-old said that that she isn't a fan of labels such as boy, girl, or even gender-fluid.

"I'm just equal," she told Time Magazine "I'm just even."

She went on to explain that it had "nothing to do with any parts of me or how I dress or how I look. It's literally just how I feel."

The Wrecking Ball songstress added: "People try to make everyone something. You can just be whatever you want to be."
