Now we know why she was wigging out in NYC back in May!
Rihanna's final collection for MAC Cosmetics will be available (and will promptly sell out) in December, but until then there's this seksi ad to whet your makeup appetite!
With her RiRi Woo red lips and matching nails, the Barbadian beauty makes biting down on her thumb look like the HAWTEST thing ever!
And thanks to the platinum blonde bob, this ad presents a totally different look from the previous ads, while the collection itself will include the super popular RiRi Woo shade as well as two new shades called Pleasure Bomb and Bad Girl RiRi.
There's also an eyeliner called Pisces Persuasion, because you know how much Rihanna LURVES her Zodiac sign!
Ch-ch-check out all the pieces in the upcoming collection in the gallery (below)!
