She has the kind of figure bikinis were made for – and a lifestyle that allows her to wear them.

But all that beach time has left Rosie Huntington-Whiteley with some rather noticeable tan lines, which were on show as she attended the Critics’ Choice Awards on Sunday.

In a backless black dress, the model’s white bits could easily be seen as she joined fiance Jason Statham on the red carpet.

Putting her best foot forward: The model put on a very leggy display in her gown as she cosied up to her leading man who was also wearing Saint Laurent

Despite this the 28-year-old was a complete showstopper, turning heads in a jaw-dropping black dress that left little to the imagination while still being incredibly elegant.

The leggy British model covered her slender, willowy curves in the floor-length backless gown, complete with a split almost to her hip on the skirt, allowing her to show off her enviable long legs.

She also showed off a hint of her cleavage thanks to the asymmetric cut of the plunging neckline, while more glamour was added with a long, floor sweeping train.

Rosie kept the rest of her ensemble simple, holding a studded YSL clutch and adding even more height to her lofty frame with a pair of barely-there strappy silver heels.

Rosie and Jason – who have been an item for five years – revealed their engagement news a week beforehand, as they walked the red carpet at the Golden Globes the previous Sunday evening.

The star had knowingly flashed her huge engagement ring while at the prestigious event – this time wowing in a golden gown – and a spokesperson for the star later confirmed their happy news to MailOnline.

 

 

 

However, the details of their proposal are not yet known, but the couple had just returned from an idyllic holiday together in Thailand.

Meanwhile, joining the Brit contingent on the red carpet at the Critics’ Choice Awards on Sunday was stunning actress Dame Helen Mirren.

Also cutting a mighty fine figure was Brit beauty Kate Beckinsale, who was a glittering goddess in an eye-catching silver gown.

The brunette beauty, 42, showed off her slim and shapely figure in the full-length gown, which glittered under the late evening sunlight in the Californian city.

Complete with a halter-style neckline and a sheer panel over the front to reveal a hint of her ample cleavage, the lightly patterned art deco-effect frock clung tightly to her tight, toned curves.

She wore her locks swept up into a classic up-do – a huge twisted bun at the back – with her long fringe parted over her perfectly made-up face.

A long way from Downton! Joanne Froggatt made her presence known in a glittering blue column gown

Kate – who is believed to have ‘secretly separated’ from husband Len Wiseman at the end of last year – turned up the heat as she cut a solo figure while making her way into the star-studded ceremony.

Meanwhile, Downton Abbey favourite Joanne Froggatt continued in a glittering blue strapless column gown, giving her a serene mermaid look about her.

The 35-year-old – who is best known for playing lady’s maid Anna Bates on the period drama – showed off the back of the lovely dress with panache, revealing its ruffled back.

She wore her bright blonde locks in a seriously chic ‘do, tied into an elegantly curly low ponytail and with her fringe elevated into a flattering retro quiff.

 

 

 

Other famous Brits in California for the annual awards ceremony included Homeland hunk Damian Lewis, who attended with his gorgeous wife Helen McCrory, and actor-turned-chat show host James Corden.

Damian, 44, looked dapper in a fitted black overcoat worn on top of a suave suit, while Helen, 47, wowed in a floor length semi-sheer green dress with black detailing and a pair of strappy heels.
