Sienna Miller turned heads in a vibrant faux fur coat during a lively photoshoot with a friend in London on Thursday.

The 43-year-old actress radiated happiness as she showcased her style in a £265 Desigual jacket.

Miller complemented the colorful outerwear with crisp white tailored trousers and sleek black leather loafers.

Adding a touch of wild flair, she completed her ensemble with a pair of leopard-print sunglasses.

Strolling through the streets of the city, she linked arms with a friend dressed in a chic Prada coat.

Sienna welcomed her first child with her partner, Oli Green, 28, last year, after they began dating in 2021. She is also mother to daughter, Marlowe, 12 from her relationship with Tom Sturridge.

Oli, who is 15 years her junior, has starred alongside Florence Pugh and Morgan Freeman in 2023’s A Good Person, and Elizabeth Debicki, Imelda Staunton, and Dominic West, in an episode of The Crown the same year.

Previously speaking about Oli, Sienna told Harper’s Bazaar: ‘I didn’t expect to take it seriously and then quite quickly, I fell in love.

‘I wasn’t like, “I’m gonna get a younger boyfriend.” It was more, “F***! Why are you young? That’s so annoying.”

‘There is a difference in the way that generation of men respect women. It’s specific to him, he is very wise and well-adjusted, but I do believe it’s also that generation.

‘They have grown up with a slightly more level playing field. I see it in his female friends as well as in the men.’

Sienna previously dated Tom, 39, for four years and split in 2015. They are still on good terms, with Sienna calling Tom her ‘best friend’.

Meanwhile, the actress was recently pictured hanging out with her on-screen husband, Dominic West, as they enjoyed a break from filming their new Sky drama War.

The pair play a couple at war on screens as they battle through an increasingly messy and scandalous divorce.

Exclusive pictures show they have a more relaxed relationship than the troubled characters they play in the hotly anticipated series.

As soon as the cameras stopped rolling, the pair were seen laughing together – a world away from their on-screen froideur.

Wearing a black dress and red lipstick, and with her hair swept up in an elegant bun, Layer Cake star Ms Miller shared a joke with her suited co-star before they returned to their roles.

Dominic, 56, and Sienna are understood to know each other well and have previously worked together, most notably on a 2005 West End production of Shakespeare’s As You Like It.
