Rosie Huntington-Whiteley shows off her sophisticated style in a backless black jumpsuit at the launch party of £280 skincare product in London

Rosie Huntington-Whiteley flashed her back in a sophisticated outfit at a skincare product launch party in London on Wednesday night.

The British supermodel, 37, attended a dinner party at the Tate Modern museum to celebrate the arrival of the new Noble Panacea eye lift concentrate.

Rosie’s stylish jumpsuit was backless and off the shoulder with one long elegant sleeve and a high halter neckline.

The supermodel accessorised with a cluster of sparkly bangles on her left hand, high heeled black sandals, and a simple black clutch bag.

Her hair was styled down in natural looking waves and her makeup look included a glossy lip, black mascara on her lashes and pink blush on her high cheekbones.

The former Victoria Secret Angel was joined at the dinner by British-American ballet dancer Eric Underwood, 40, and American fashion designer Connor Ives, 28. 

The £280 cream, consisting of 12 doses, costs a pretty penny as the only skincare brand created by a Nobel Laureate scientist.

It promises to reduce wrinkles, treat eye bags, and combat dark circles under the eyes.

Rosie is engaged to British actor and former professional swimmer Jason Statham, 57, who is twenty years her senior.

Jason earned £32 million last year, as much as Leonardo diCaprio, and lives with Rosie in a £7.5million property in Cheslea, London.

The couple have been engaged since 2016 and together have two children – a son named Jack, 7, and a daughter named Isabella, 2.

It comes after Rosie packed on the PDA with her fiancé Jason Statham as the couple posed for a slew of loved-up snaps from their family holiday in Antiparos, Greece last week

In the romantic carousel the actor and Rosie look every inch of the happy couple while taking turns to stamp a smooch on each other’s cheeks.

In the radiant series of snaps from their Greek getaway, the lovebirds looked carefree struggling to contain a spontaneous laugh.

Rosie also shared a rare vacation snap with the Fast X star and their daughter Isabella , 2.
