Miley Cyrus has launched a new MAC lipstick to help ''end AIDS''.

The 22-year-old singer is the new face of the makeup company's Viva Glam lipstick and tinted 'lipglass', which are helping AIDS, as every sale will go towards MAC AIDS Fund.

Along with the advert for the new campaign, Miley shared: ''Help to end AIDS with my new @MACcosmetics #VIVAGLAM lipstick available online in North America on 9/8.''

The 'Bangerz' hitmaker - who is known for her short pixie crop - is seen sporting a long platinum blonde hairdo in the advert, along with the MAC lipstick, a pair of tiny shorts and an off-the-shoulder crop top.

Other celebrities who have launched exclusive Glam product lines in the past include Sir Elton John, Nicki Minaj, Ricky Martin, Lady GaGa and Rihanna - who raised over $50 million for the MAC AIDS Fund.

The 'FourFiveSeconds' hitmaker designed two lines of Viva Glam lipsticks and lipglasses for the cosmetics brand, which was then sold to raise money to support those who suffer from the deadly disease.

Announcing the news, the brand's official Twitter account read: ''And...congrats to @rihanna on raising $50 mill+ for @MACAIDSFund during her 2014 #VIVAGLAM reign. Most ever in one year!''
