Rihanna's 'RiRi Woo' MAC Lipstick Debuts Thursday

Get ready ladies -- Rihanna's much-hyped "RiRi Woo" lipstick, her own version of MAC's popular matte red shade Ruby Woo, will be available for purchase starting tomorrow.

Though Rihanna will be releasing an entire MAC collection throughout 2013, her first product -- a lipstick which is described as a matte cool red -- is definitely the most anticipated given the popularity of MAC's original shade and Rihanna's own signature red lips.

"Working with MAC, it's difficult to get a red lipstick that beats Ruby Woo, because it works on every skin tone," Rihanna told WWD. "I had so many different samples to choose from and so many different colors underneath -- blue, yellow, orange and pink bases. And I got to pick one that worked, and I tried it on all my friends to make sure it worked on all of our skin tones."

And one look at the lipstick in action confirms that the shade is indeed gorgeous!

Rihanna's first foray into lipstick -- which retails for $15 a tube -- will only be sold exclusively online or in person at Rihanna's concert in Brooklyn's Barclays center.

But do you think Rihanna's MAC shade will out-sell Nicki Minaj's MAC collaboration, which became the best-selling Viva Glam lipstick of all time?
