You Have To See Ariana Grande's MAC Collaboration

Still got leftover dough from the holidays? Ariana Grande's M.A.C Cosmetics collaboration is dropping soon, and this is a collection worth saving (and waiting) for. Get ready to see your beauty cabinet grow, one lippie at a time.

For the pop songstress who perfected the cat eye and revolutionized the high pony, entering lip territory is all kinds of new. Grande is M.A.C's newest "Viva Glam" brand ambassador — a title previously held by Miley Cyrus, Lady Gaga, Rihanna, and Fergie to name a few. The starlet's collection includes two lip products: a shimmery pink lip glass and a matte plum lipstick. Sweet and sugary by day, dramatic and smoldering by night? Hello, foolproof lip combo.

Being ambassador comes with a powerful responsibility: creating makeup for a cause. In October, Grande divulged the news on Instagram — lipstick emojis and all.

#VIVAGLAM @maccosmeticsI am beyond honored and excited to be working with a brand that stands for and always has stood for EQUALITY. my lipstick & gloss will be available in January and EVERY PENNY goes to people effected by HIV & AIDS. 💕💄💕💄💕💄 I have loved & supported @maccosmetics ever since I was a little girl walking through the mall and saw your first #VIVAGLAM girl in the window @rupaulofficial. I'm so honored!!!

That's right: purchase an Ariana-approved lip product and you will be supporting the M.A.C AIDS Fund. All proceeds from the Viva Glam collection will go to assisting people living with HIV/AIDS.

The Ariana Grande and M.A.C Viva Glam collection is available in-stores and online. Not only will you be rocking the most stylish pout of the new year, but you'll be lending a hand to those in need. The best way to ring in 2016 indeed.

The colors are the epitome of Ariana essence — a moody intense plum for your inner bad girl, then a sparkly delicate pink for your innocent side. Playing devil and angel has never been easier.

Clearly, Ariana Grande can now expand her resume from cat eye expert to lipstick whisperer.
