Sienna Miller showed her support for close pal, and her ex’s new fiancée, Alexa Chung on Tuesday night.

The pair cuddled for snaps at Tollington’s Fish Bar in Finsbury Park to toast the new The Edit by Alexa Barbour collection with rounds of negronis and martinis.

The intimate guest list also included Alexa’s fiancé Tom Sturridge, who is Sienna’s ex as well as the 43-year-old actress’ boyfriend Oli Green, 28.

Alexa was seen raising a toast amongst her pals as she celebrated her second capsule collection for the British heritage brand which has a nod to the style icon’d legendary festival styling.

The guests wore pieces from the collection with Sienna looking gorgeous in a pale pink coat, whilst Alexa, 41, rocked a striped knit before changing into a lace-trimmed black slip dress and red coat.

Tom, 39, and Alexa went public with their romance in July 2023 when they attended day seven of the Wimbledon Championships.

In a nod to their very unique set-up, in their first public outing, they were joined by Sienna who looked joyous while sitting in front of the couple.

Tom and Sienna previously dated 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 Layer Cake 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.

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.’
