The 28-year-old singer is styled like a retro golden goddess in the newly-released teaser shots from the campaign and the collection will no doubt be an instant sell-out when released.
Goulding gave fans a sneak peek of the range on 4 June when she made the announcement by sharing the photo above on Instagram, and it soon received more than 165,000 likes.
She captioned the snap: "Oi oi SO excited to finally share what I’ve been working on with @MACcosmetics!!! #MACEllieGoulding drops in Dec/Jan!".
The Ellie Goulding x MAC collection will include a peachy pink lipstick, a shimmering champagne gloss, and a rose-gold lip and cheek crayon. There's also a smoky neutral eyeshadow quad, corner lashes and a bronzer/blusher duo on offer.
The Hereford-born star is in good company with the cosmetic brand, joining their star-studded line up of previous ambassadors including Rihanna, Miley Cyrus, Nicki Minaj and Lady Gaga.
