Rihanna just debuted an oh-so-fierce ad for her Rogue fragrance. Going grey just wasn't enough this week huh, RiRi?

The pop diva keeps giving us more and more instant-glam on Instagram. The Bajan beauty posed in nothing but high-waisted underwear, ankle-strap heels and signature shaved 'do. How daring darling! 

This is the kind of shot that makes even the bottle look good. That's how you work your sexy! RiRi bares enough skin to draw attention, but leaves just enough covered to leave a little to the imagination. 

We now want to know more about her fourth fragrance.The highly-anticipated scent has a "flirty, sensual Oriental aura," and comes in a vial complete with inverted studs, said our friends at MTV Style. It will hit stores in September, but we want it now! 

If RiRi's already got ya into Rogue, let us know in the comments section below.
