MAC have had no shortage of celebrity collaborations this year, Lorde and Mia Moretti to name just a few, and for its latest collaboration the brand has enlisted none other than pop princess Rihanna.

The star took to her Twitter account yesterday to share the news, tweeting: “Check out my new @MACcosmetics #VivaGlam ad. All sales go to people affected by HIV/AIDS. Comin @ ya this September!!”

However, this isn’t the first time Rihanna has collaborated with the brand; her first collaboration, released last year, included a sold out lipstick. Earlier this year, she released a range entitled Viva Glam.

In contrast to the stark red shades we saw in the Viva Glam range, the new range will include a nude coloured lipstick and gloss.

As mentioned in the tweet, all of the profits made from the sales will go towards helping men, women and children affected by HIV and AIDS.

The collection, entitled Viva Glam II, will be available to buy from all MAC locations from September 2014.
