CosmoGIRL returns for the first time in almost 20 years and is fronted by fan-favourite character Rosalina.

The limited-edition issue was distributed across major UK retail and city locations, including Westfield Stratford, Trafford Centre, Metrocentre, and high streets in Birmingham, Leeds and Manchester.

The collector’s edition features an exclusive interview with Oscar-winning actor Brie Larson, who voices Rosalina, alongside editorial content inspired by the film, including a dedicated guide, horoscopes and nostalgic Cosmo features.

The campaign also included a premium experiential moment, with Cosmopolitan hosting an exclusive screening for Club Cosmo members at The Cinema at Selfridges.

Social-first content extended the campaign further, with creators Rosie Okotcha, Meg Hughes and Rosie Caddick producing content designed to capture fan engagement and community, including a Rosalina-inspired “get ready with me”, a “come with me” screening experience, and interactive Super Mario content.

Natasha Banjo, Portfolio Director of Cosmopolitan UK, said: “Partnering with Universal Pictures International UK & Eire Limited on The Super Mario Galaxy Movie brings together a global entertainment franchise with Cosmopolitan’s ability to engage young women at scale. By combining the return of CosmoGIRL with live experiences and social-first storytelling, we’ve created a campaign that connects nostalgia with a new generation of audiences.”
