Her knight in shining armour! King Arthur star Poppy Delevingne is joined by husband James Cook as she leads the glamour in sweeping red jumpsuit at Jo Malone launch party

She takes a key role in Guy Ritchie’s critically panned new film, King Arthur: Legend of the Sword.

But Poppy Delevingne, 31, was joined by an altogether different knight in shining armour as she helped perfume brand Jo Malone London launch their new digital platform, website The Talk of the Townhouse, in London on Thursday evening.

Accompanied by husband James Cook, the statuesque model caught the eye in a stunning red flared jumpsuit as she made an entrance at the on-off celebratory event.

With a cinched waistline, the sleeveless outfit drew attention to Poppy’s slender physique as she posed for photos alongside guests including Arizona Muse, Courtney Love, Jeremy Irvine and Poldark star Eleanor Tomlinson.

Poppy serves as a Jo Malone London Girl for the brand, along with English model Karen Elson, who was in attendance on the night.

Cara's sister Poppy certainly made sure she was centre of attention in bold red, adding a choker necklace that proved to be an equally striking accessory.

Her willowy blonde locks were centre parted and pushed behind her ears to reveal her pretty features.

Allowing her vibrant outfit to dominate, Poppy selected her make-up from a subdued colour scheme that served to accentuate her delicately proportioned features.

The model, who plays King Arthur's mother Igraine in director Ritchie's poorly received new film, completed her look with a pair of tasteful cross earrings. 

Poppy said of the evening: 'Tonight was made up of all my favourite things, rolled into one humdinger of a house party; pals, flowers in abundance and of course, fragrance.' 

Joining Poppy on the night, fellow guests included Zara Martin, Candice Lake and American singer and actress Courtney Love.

The former Hole front-woman, 52, opted for a comparatively relaxed striped sweater and garish, galaxy patterned skirt.
