Are you ready for more Ri-Ri? Wait, don't answer that. What if I said, "Are you ready for more Ri-Ri MAC makeup?" That sweetens the deal, doesn't it? Good, because this October, MAC is launching its third collaboration with the "Diamonds" singer.

Best we can tell? It's very ... pink -- well, the cases anyway. The eyeshadow itself seems to be a pretty palette of pinks and browns, and the collection also includes a bronzer, and a mascara. Our fave addition to the collection? The dark and mysterious Ri Ri Woo Woo shade, which is coming back in lip gloss form this time around.

The pieces retail for between $16.50 and $44, and will be available online October 2, and in stores October 3 through October 31 -- so don't sleep on this! [Yahoo Shine]
