Machine Gun Kelly enlisted the help of his fiancée Megan Fox for the latest UN/DN LAQR campaign, and it feels like he made the right decision.

Developed in partnership with Fox, the new nail polish collection draws inspiration from her favorite crystals and gemstones, featuring jewel-toned shades like ruby red, royal blue and emerald green. According to the brand’s press release, each shade was carefully curated to evoke confidence, Sєxiness and feelings of being centered.

Fox recently spoke to Allure about the collection, sharing that the metallic green, dubbed ‘Brutal Honesty,’ “has a strong Sєxual energy that helps me feel aligned with my heart and my truest desires.” The color is also reminiscent of Fox’s engagement ring, which boasts a striking metallic finish.

The collection is available through a new ‘Play With Fire’ kit, which includes shades Twin Flame, Past Life, Brutal Honesty, Third eye, Deep Break and Nothing (Matte)rs Top Coat. Elsewhere, fans can shop ‘The Big Bang Set’ which includes Past Life, Brutal Honesty and Deep Breath.

The new Megan Fox x UN/DN LAQR collection is now available for purchase from the brand’s website.
