By now most will probably have already seen the image of the first part (I believe there will be four collections in total) of Rihanna's collection for MAC?
Like most I'm a little disappointed the packaging well at least from the leaked image appears to be rose gold plastic and rather than looking swish/sophisticated it looks cheap and perhaps better at home in Poundland
rather than MAC.

That being said look a little closer and the shades of the cosmetic items do actually look appealing, a deep plum almost black lipstick, a deep red lip gloss and an eyeshadow palette full of neutral shades.
Yes at closer inspection it isn't too bad but as Rihanna prides herself on being edgy/controversial the packaging is on the safe side and bland...it almost looks toy like?

Truthfully I knew it would only be a matter of time before MAC and Rihanna collaborated, I initially thought it may have been for Viva Glam but they re-signed Nicki Minaj so I guess this collection is of little surprise.
I'm not sure why they have decided Rihanna needs four separate collections though?

Yes it will sell out as most MAC collections do but at this instant i'm not a fan and it will take a few special shades to tempt me to spend any cash on any of the mini collections I'm afraid!

A little extra information from WWD:

"The four collections, to be known as RiRi [Hearts] MAC, will break throughout 2013, and current plans call for 31 stockkeeping units. In another first, MAC is calling Rihanna, who turns 25 years old today, a “creative partner” rather than a collaborator. Her name will appear on the packaging, and her signature will be embossed on the RiRi Woo lipstick case and on the bullets of the summer lipsticks, as well as several of the fall and holiday pieces.

RiRi Woo will be sold at the Rihanna concerts and online, and a summer collection will follow, which will also be sold online. A third will land in brick-and-mortar stores for fall, and there will be an on-counter holiday collection. 

The signature piece of the lineup, RiRi Woo, will be sold with all four collections. The summer collection also includes two additional lipsticks, a Lustre Drops shade and a powder blush duo. Fall’s 16 sku’s include four lipsticks, a deeply pigmented Lipglass version of RiRi Woo, two multishade eye shadow palettes and false lashes. (“She likes to wear two pairs at a time,” said Jennifer Balbier, MAC’s senior vice president of global product development, in an aside.) Holiday will bring another 10 items, including nail polish, a makeup bag and additional lipsticks."
