The 'Diamonds' singer's Fall range only hit stores a couple of weeks ago, but she's already been hard at work creating new products for the brand.
The RiRi Hearts MAC Holiday collection hits stores in December, and we've no doubt it'll be sky-rocketing to the top of our Christmas lists.
The range sees the return of the now infamous RiRi Woo Lipstick, £16.50, a cool matte red, plus the matching nail lacquer, £12 (as worn by the lady herself in the promo picture).
There will also be a bright fuchsia lippy called Pleasure Bomb and a taupe nude named Bad Girl RiRi.
Fans can look forward to two new eyeshadow palettes featuring five strips of colour, £33 each, along with two liquid liners, £18.50 each, in a shimmery rose gold and a frosty white.
We've got our eyes on the double-ended brush, £27, which has a MAC 217 on one end (loved by make-up artists for blending out shadow) and a MAC 239 on the other (fab for packing colour onto the lid, smudging eyeliner or applying shadow under the lower lashline).
RiRi has also added a quilted make-up bag, £25, to her collection, along with a golden brown bronzer named Love, Rihanna, £22.
As per usual the starlet looks positively stunning in the campaign image, rocking a fierce blonde crop and winged-out eyeshadow.
Clearly proud of her new range, Rihanna recently tweeted: "MAC Girlz, you already know you HAVE to be early to get this before its sold out!!! #HolidayCollection #RiRiHeartsMAC #ComingSoon #DECEMBER #2013."
The collection will be exclusive to Selfridges from 5 December, before rolling out into all MAC stores on 12 December.
See you in the queue!
