Katy Perry Is Launching New CoverGirl Makeup Inspired by Mermaids!

The Katy Kat Eyeliner is a double-ended pencil featuring a longwear "liquid pencil" formula on one side and a smudger tip on the other. Use it to up the drama for your after-hours makeup. While there are four shades eventually launching, only two are available this Spring. The green and silver shades will be launching in March, while you'll have to wait for the matte and glitter black versions.
