The chanteuse took to Instagram to excitedly share the below post with her followers, "It’s a major lip #moment!," she wrote.
"'All I Want' lipstick with @MACcosmetics is coming Dec. 2015! Plus, a full Mariah x MAC Beauty Icon collection is coming later in 2016!"
The first product is a lipstick called All I Want, a frosted champagne nude which Carey describes as "elegant, sophisticated, and glamorous.”
The lipstick will be released just in time for Christmas (hence the completely adorable name).
“MAC has been my go-to makeup brand for as long as I can remember, and I’m so thrilled to be collaborating with them on a lipstick debuting this December, just in time for the holiday season!” Carey said in a press release from the brand.
There's no word on what the full collection will bring yet - perhaps an eye palette filled with smokey taupes? A peachy blush and fierce bronzer? Obsession-worthy lashes? Butterflies on everything? We're screaming.
