While her fashion choices range from impeccable to downright ridiculous, there's one thing that Rihanna never gets wrong.
Whether she's sporting a smouldering, smoky eye or a brightly-coloured lip, the girl always seems to look gorgeous - so gorgeous in fact that M.A.C have once again joined forces with the star for the launch of a new lipstick.
Rihanna is the new face of Viva Glam, having designed a new shade of lipstick and 'Lipglass' lipgloss for the company, which will donate 100 per cent of the purchase price to fighting HIV and AIDS.
The 25-year-old singer, who names lipstick as her must-have accessory, says the collaboration came about after the success of RiRi Woo (a true matte red lipstick from her 2013 line with M.A.C).
"If these lipsticks were so successful, imagine how much we could help people with HIV and AIDS," she said.
According to Rihanna the difference between her previous sell-out shade and the new Viva Glam product comes down to "a little bit of frost, so the texture is more shiny - not as matte as RiRi Woo."
"Because the proceeds of the lipstick are going to the M.A.C AIDS Fund, it was very important that this lipstick could work on many different complexions," she said.
Earlier this month Rihanna tweeted a sneak peak of the Viva Glam campaign:
