With RiRi Woo, her take on MAC's iconic Ruby Woo red lipstick, selling out three hours after being made available online, it's clear Rihanna's RiRi Hearts MAC collection is going to be a hit. Images of Ri's new shades of lipstick and illuminating drops have landed online and we're gawking at them.

That's RiRi Woo on the far left, while the other lipstick shades are RiRi Boy (a matte mauve) and RiRi Heaux (a rich burgundy). The lipstick bullets are stamped with the 'Stay' singer's signature, as well. It's an artsy added touch. Plus, the colors are vivid and would suit any skin tone.

The Lustre drops add shimmer and shine to your face, decolletage and other areas of bare skin. It's an added dose of dewy sexiness.
