Rihanna stepped out on Tuesday night as MAC's Viva Glam Cosmetics ambassador, showing her support in the fight against AIDS at the premiere of Andrew Jenks' new documentary It's Not Over.

"[I'm] very excited, very honored [to be here]," she said. "This is gonna be an amazing event for an amazing cause, an amazing film. This documentary, It's Not Over, is really gonna be educational for the youth [with] what's going on and how they're affected by HIV/AIDS all over the world."

The film, which premieres on Netflix and Pivot on Nov. 19, follows three young people from different corners of the world who are affected by HIV/AIDS.

"I think a lot of people from my generation, including myself, didn't realize that the epidemic was in such a dire state," filmmaker Jenks told ET. "So it was a great challenge to take on and then to be able to film all over the world and get to know all these different people -- it's important."

The bottom line is we need young people to watch this film and we need to create a movement, and she's an incredible fuel in that movement."
