Hayley Atwell wows in a sheer black blouse amid speculation she secretly welcomed her first child as she attends Fendi event alongside glam Sugababes star Mutya Buena

Hayley Atwell cut a chic figure in a sheer black blouse as she posed at a Fendi event in London on Wednesday amid speculation she secretly welcomed her first child with fiancé Ned Wolfgang Kelly.

The actress, 42, was all smiles as she flashed her black bra beneath the sheer top while mingling with other attendees at the fashion brand's Winter Holiday 2024 Collection Launch.

Hayley was in good company at the VIP party as Sugababes star Mutya Buena was also in attendance, dressed to impress in a glam cream and black ensemble.

Mission Impossible 8 star Hayley - who was recently seen with a baby amid pregnancy rumours - added a smart pair of black trousers and pointed black heels to her look, while holding onto a black leather bag.

As she made her way into the fashion event, the beauty covered up in a furry-trimmed black jacket, which was gracefully draped over her shoulders.

She looked in great spirits as she posed with actor Jimmy Akingbola inside.

Meanwhile, Mutya, 39, rocked a similar look to Hayley, also flashing her bra beneath a sheer black top by Fendi.

The Round Round hitmaker added an oversized cream jacket and coordinating trousers, finishing off her ensemble with black heels and nude miniature handbag.

Other attendees included Gene and Lennon Gallagher, Yasmin Finney, Wretch 32 and Nick Grimshaw.

Just a day before, Hayley put on a loved-up display with her fiancé Ned on Tuesday night, as they attended the star-studded re-opening of The Georgian at Harrods.

The actress exuded elegance at the event in a black satin gown, gathered at the waist to showcase her svelte figure.

Adding a pop of colour to her monochrome ensemble, the Marvel star added a pair of bright red high heels.

The couple - who were first linked in July 2022 - have kept their relationship away from the public eye and are rarely pictured together.

Ned popped the question to Hayley in Venice in April 2023, and the pair are thought to have welcomed their first child together this year.

The Mission Impossible star sparked speculation she was to become a mother after she was seen cradling her tummy during another trip to Venice with Ned in April this year.

And on Tuesday last week, Hayley was photographed stepping out with her baby for the first time, as she lovingly cradled her little one on a visit to a London park .

Confirming their engagement last year on Instagram, Ned wrote: 'Lucky me. Arrived in Venice at 10am, around midday the love of my life and I got engaged in the kitchen of this strange apartment surrounded by ducks, with a bloke outside the window murdering "My Way" on the accordion.

'A perfect start to the rest of our lives together. I'd never had any interest in getting married... until I met this extraordinary woman. Happy as a clam.'

While speaking to the Daily Mail's Richard Eden, Hayley described Ned's low-key proposal, recalling: 'My fiancé was in his pants in the kitchen, and there was an accordion playing outside our window — which was timed perfectly but not planned.

'We had rented this Airbnb that had lots of shelves with porcelain ducks on them, so it was quite a surreal set-up.

'I said to him, "Venice was my first most precious destination", and I've always had a weird connection with it. So, he took me there, and it happened there.'
