It's Official: Ariana Grande Lands MAC Cosmetics Partnership

And ... "It's guilt-free shopping"

After much anticipation, MAC Cosmetics announced its new Viva Glam girl on Periscope -- and it's a very "excited" Ariana Grande.

"The new Viva Glam MAC girl is me!" Grande said. "... I'm so excited, thank you MAC."

As the newest Viva Glam girl, Grande created two new MAC colors: a dark matte plum lipstick and a shimmering pink lip gloss. Grande says these colors will allow MAC-wearers to channel both their inner "bad girl" and "good girl".

"I think you should be able to play up both sides," she said.

As always, 100 percent of Viva Glam's proceeds will be directed to the MAC AIDS FUND. Grande is among former Viva Glam-ers including Ru Paul, Fergie, Nicki Minaj and most recently Miley Cyrus.

Grande, who recently debuted a new fragrance Ari by Ariana, says her lip colors should be "guilt-free shopping".

"The best part is, 100 percent of the proceeds goes to the MAC AIDS Fund," she added.

Here's to the good and bad girl in all of us.
