We learned way back in October 2015 that the 22-year-old would be the next spokesperson for the brand's line, which gives 100 percent of proceeds to the MAC Aids Fund, and now it is finally available for purchase in select stores and online. But before choosing which items to throw in the shopping bag, buyers—and Grande herself—have a very important decision to make. In the latest campaign visuals the singer is seen teetering back and forth between being a good girl or a bad girl. Her sweet and innocent side wants to get glammed in shimmering pink MAC Viva Glam Lipglass ($15; maccosmetics.com), while her wild and dark tendencies crave the deep matte plum Viva Glam Lipstick ($17; maccosmetics.com). It's definitely a tough decision to make, as both shades look amazing on the "Bang Bang" singer. The only way to settle this dispute is to just test out both gorgeous colors on yourself.
