Sienna Miller, Alexa Chung and Jo Wood cut casual figures in jeans and jackets as they arrived at Fran Cutler’s birthday bash at Nexus Club London on Thursday.

Actress Sienna, 43, looked effortlessly chic as she arrived at the celebrations wearing a white slip dress under a brown woollen jumper.

Putting on a leggy display, she paired her slit silky one piece with a pair of chunky brown leather knee-high boots.

The blonde beauty toted around her belongings in a silver-grey leather tote bag as she styled her luminous tresses into loose beach waves.

Model Alexa, 41, channelled 90s style trends in a pair of low-cropped jeans, which she paired with a lacey black top which was hooked in the center of her midriff.

She layered a long leather, fur-lined black coat over the skimpy top as she added inches to her statuesque frame with a pair of black pointed heels.

She kept her accessories to a minimum for the outing, as she wore two dainty necklaces and a handful of gold rings.

Meanwhile, PR supremo Fran, 62, who has had a rocky relationship with her formal best pal Kate Moss over the years, commanded attention in a pair of thigh-high leather lace-up boots.

The former socialite paired her towering boots with a skimpy silky black dress as she celebrated her big night with some of London’s biggest A-listers.

Sienna’s outing comes after she has been seen looking smitten with her younger boyfriend, Oli Green, in recent months.

The Layer Cake actress and the Bridget Jones star, 28, have been spotted at some of the biggest events of the year, including Paris Fashion Week.

The happy couple welcomed their first child together in 2023. 

Speaking to Harper’s Bazaar about Oli, Sienna said: ‘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*ck! 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 Sturridge for four years and split in 2015. They are still on good terms, with Sienna calling Tom her ‘best friend’ whilst they co-parent their daughter Marlowe, 12.

Sienna has given her seal of approval for her ex and Alexa  and in December told Vogue UK: ‘I’m really happy for them. It’s genuinely lovely.’

The actress even joked about their co-parenting situation and revealed that their daughter Marlowe has brought one of Alexa’s jumpers home, which she has since claimed for herself. Sienna quipped: ‘I’ve got one upstairs!’

Following their split in 2015, it was claimed Sienna and Tom had different goals. A source said: ‘Tom wanted to get married and have more children. Sienna didn’t.

Last year Alexa and Tom sparked engagement speculation when they were seen wearing matching rings.

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.’ 

Meanwhile Sienna welcomed their first child together last year after they started dating in 2022.
