Ariana Grande is naughty and nice in a new ad for MAC Cosmetics' Viva Glam lip collection.

The 22-year-old pop singer was named a spokesmodel for the brand in October, during which the company released a first ad for the campaign, which showed her wearing dark plum lipstick, a black crop top, black short shorts, thigh-high black boots, plus her signature high ponytail.

In a new animated image released on MAC's Instagram page on Wednesday, Grande pouts while sporting the same look in one slide, showcasing her inner bad girl, and appears demure while wearing a bright pink gloss, a matching top and nail polish, plus a pink streak in her hair.

"Good girls, bad girls, go glam!" the caption reads.

All proceeds from the Viva Glam collection of lipsticks and lipglasses are donated to the MAC Cosmetics Aids Fund.
