Rosie Huntington-Whiteley for Harper's Bazaar

Rosie Huntington-Whiteley is obviously a fan of the mantra - the bigger the hair the closer to heaven.

And the model demonstrated just that as she appeared on the cover of Harper's Bazaar's annual spring fashion edition wearing a particularly voluminous look.

The model, Karl Lagerfeld and Carine Roitfeld have collaborated on the coveted March issue of Harper’s Bazaar, and Rosie takes centrestage on the cover for the special issue of the magazine.

The avid gym bunny showed no qualms as she posed topless for the style issue, save for a few strategically placed beads.

Former Vogue Paris editrice Carine, international editor at large for Harper’s Bazaar, collaborates on this special issue once a year.

And her chosen model Rosie will grace a range of Harpers Bazaar covers internationally, while the main fashion story was shot by legendary designer and photographer Karl Lagerfeld.

It's a stunning return to high-fashion for Rosie who looks supremely elegant after a 50s style makeover, complete with hot pink lips and a fluffy pink cashmere sweater on the cover of Carine's Edit.
