Alexa Chung cut a typically chic figure as she arrived at The Platinum Card by American Express x Vogue Supper Club at Toklas on Tuesday night.

The model, 40, looked gorgeous as she donned the strapless black mini dress for the star-studded event at the mediterranean restaurant.

The TV presenter kept her outfit simple and added a pair of pointed black stilettos with bow details to her look.

Alex wore minimal jewellery, simply accessorising with just a couple of gold rings, while letting her simple but elegant dress do the talking.

Alexa posed up a storm as she rubbed shoulders with Bridgerton's Martins Imhangbe and It's A Sin's Lydia West.

Martins, 33, looked dapper in an Hermès SS24 sheer white jacket and tailored charcoal grey trousers as he smiled next to Lydia, 31, who wore a silk maxi skirt and black crop top. 

She added an oversized blazer to the look and finished off with a pair of dainty peach satin kitten heels covered in gems, and a bright red bag matching her bold red lipstick. 

Alexa also partied the evening away with fellow model and author Jack Guinness who looked suave in a black double breasted suit and vest.

Designer Marco Capaldo was also in attendance and cut a relaxed figure in a pale yellow crew neck jumper.

The favourite designer of Zendaya finished his look with a pair of black trousers and leather ruched loafers. 

The Gentleman actor Harry Goodwins cut a smart figure in a baggy double breasted navy suit as he joined a host of famous faces for the evening.

It comes after it was revealed Alexa is reportedly engaged to boyfriend Tom Sturridge following months of rumours.

The star first sparked engagement rumours with the actor, 38, back in June, with the couple seen wearing matching rings in October.

Now, the couple are said to be 'over the moon' and are planning a 'classy' wedding ceremony in summer.

A source told The Sun: 'Alexa has confirmed to her friends that she is indeed engaged to Tom and she is over the moon.

'She is in a great place and seems completely head over heels for him. They're a great match.

'They have been hard at work planning a wedding with all of their close pals there.

'It won't be a massive over-the-top affair but a smaller, classier and cooler bash.'

MailOnline has contacted Alexa and Tom's representatives for comment.

Back in February, Alexa stepped out wearing bridal white and flashing a ring on her wedding finger as she attended Paris Fashion Week.

Posing for photos ahead of the Christian Dior Fall/Winter 2024-2025 ready-to-wear show she teamed a plunging satin blazer with matching high waisted trousers.

Alexa topped off her elegant outfit with a pair of black patent loafers and carried a bouclé handbag from the designer.

She styled her hair into tousled waves and opted for a subtle makeup look with a dusky pink lipstick.

Back in June, Alexa was spotted with a ring on her wedding finger, leading to speculation the couple were engaged.

The son of award-winning film director Charles Sturridge, Tom seems open to marriage, while Alexa for her part, previously mused: 'I just don't get why marriage is different from non-marriage — I just don't get it.'

Her spokesperson declined to comment when asked about the rumours.

Tom and Alexa went public with their romance last July when they attended day seven of the Wimbledon Championships.
