The 21-year-old singer took to Twitter on Wednesday to reveal that she has collaborated with the make-up giant to create a hot pink lipstick and lipgloss.
"Going #VIVAGLAM with @MACcosmetics," she wrote, as she gave fans the first look at her new campaign image. "Look for my lipstick in early 2015."
Miley Cyrus is the new face of MAC Viva Glam
Miley, who is known for her bold and fearless outfits, dazzles in a sparkling black and pink bodysuit for the images, wearing the shade of hot pink lipstick she has created, with her platinum blonde pixie cut slightly dishevelled for a striking beauty look.
The Wrecking Ball singer also revealed that all proceeds from the sales of her lipstick and lipgloss would go to charity.
"Every cent from the sales of my #VIVAGLAM shade will go to @MACAIDSFund to help people affected by HIV," she wrote on both her Twitter and Instagram accounts.
Miley joins a line of edgy Viva Glam ambassadors including Lady Gaga, Nicki Minaj, Dita Von Teese and Rihanna who have all collaborated with the cosmetics giant to create make-up in order to raise money for the brand's charity.
This is not the first collaboration Miley has unveiled this year. In September, she debuted her 'Dirty Hippy' accessories collaboration with designer Jeremy Scott, which the pair showcased during his New York Fashion Week catwalk show.
The We Can't Stop singer made an appearance at the end of the presentation, joining Jeremy down the catwalk as they celebrated.
