Rihanna just debuted her first hot ad for her RiRi Hearts MAC Cosmetics Fall collection on Instagram.

The Bajan beauty's killer pout just reigns supreme when it comes to beautiful lip looks. Rihanna is rocking a burgundy matte shade in the teaser photo, and we assume it's one of her latest RiRi MAC lipsticks from her summer range. For just $15 each, you can still get the trio of limited-edition lipstick shades in retro matte finishes: colors include a cool red of RiRi Wooa vivid lavender dubbed RiRi boy and a berry color of Heaux.

The "Stay" singer was so happy about the ad that she shared the news via social media, like most celebs.
