Viva Glam! Miley Cyrus transforms to platinum blonde siren in tiny shorts and cropped top for new MAC campaign

It's been years since Miley Cyrus sported long locks, preferring the short cropped 'do.

The 22-year-old Bangerz star got to play dress up and promote a good cause as she shared her beguiling ad for MAC's Viva Glam charity-minded collection on Thursday.

Miley was seen wearing white-blonde, waist-length wig and sporting the cosmetic company's pink lipstick and gloss, along with a pair of incredibly tiny shorts that showed off a generous view of leg and taut tummy.

A hot pink, off-the-shoulder cropped top added extra power to the overall look while a thick chain necklace wound around her throat.

'Help to end AIDS with my new @MACcosmetics #VIVAGLAM lipstick available online in North America on 9/8,' Miley wrote in the caption.

The timing is no coincidence and girls in their teens will no doubt rush to buy the lipstick and lip gloss for back to school.

Miley also posted a picture of the glamorous red lipstick and gloss that will have the ladies savouring.

Lipsticks retail for $16 a piece and the tinted 'lipglass' sell for $15.

All the money made from the sale of these Viva Glam products will go towards MAC AIDS Fund to help people with HIV and AIDS.

Miley was in a chipper mood on Wednesday when she stepped out with her younger sister Noah to have lunch at Hugo Tacos in Los Angeles' Studio City area.

Stay shady in Miley's brat pack sunglasses

Some people love her style, some people hate it. That's what comes with being a true fashion risk taker, and Miley Cyrus is certainly one of those. Not afraid to step out in bold colors and crazy prints, clashing statement pieces and ignoring the trends - Miley has created a style that's pretty unique to her.

In this casual get up, she teamed a simple vintage pink shirt with an airplane print all over, with a pair of tights and Converse and some statement accessories, including these amazing Brat Pack cat eye sunglasses. While we're also crushing on that Chanel rucksack, we'll stick with the shades seeing as they are a slightly more affordable way to steal Miley's look.

Miley's stand out sunglasses are from a collaboration between Emma Mulholland and Pared Eyewear, and currently available to buy at Nasty Gal where they are reduced to $182 (click the link to the right to purchase).

Noah, 15, who recently obtained her driving permit, also played chauffeur even though the law requires that she be accompanied by a driver who is at least 25.

And according to the DMV, 'he or she must sit in a position close enough to take control of the vehicle, if necessary.'

Miley didn't seem too concerned as she sat in the passenger seat and snapped pictures of Noah behind the wheel.
