Sienna Miller looked effortlessly stylish as she attended the Carolina Herrera X Frame party in New York City on Thursday. 

The actress, 42, was joined by her boyfriend Oli Green, 27, for the celebration which was held at Chez Margaux. 

She wore a casual ochre denim co-ordinate consisting of an oversized jacket and a matching pair of wide leg jeans. 

Sienna teamed her outfit with a plain T-shirt, a pair of Calvin Klein boxers and a grey Prada handbag. 

Oli opted for a similar look as he paired a suede jacket with black jeans and a white T-shirt.

The actress and actor welcomed their first child together earlier this year after they started dating in 2022. 

The actress gave birth to her daughter Marlowe, now 12, with her ex Tom Sturridge in July 2012.

And after welcoming her second child to the world earlier this year with Oli, at the age of 42, Sienna told Stellar Magazine that she could not recommend late motherhood more highly.

The American Sniper star welcomed their daughter, whose name she has not revealed, in January.

‘My own experience of motherhood 12 years later is completely different’ the British star told the publication.

‘I’m a very different person. People often have lots to say about having babies in your 40s as women, but I can’t advocate for it more. I feel very lucky.’

Last month, Jude Law revealed he’s ‘moved on’ from the time in his life when he was engaged to Sienna, as he posed for a suave new shoot with VARIETY.

The actor, 51, told the publication ‘that time in his life is now over,’ after his relationship was the centre of huge public attention.

Jude and Sienna split in 2006 after his affair with his children’s nanny Daisy Wright came to public knowledge in 2005, and the actress said in 2020 that she found the scandal ‘really hard’.

Speaking about the time he and Sienna were engaged, Jude said: ‘That time is now over, and I’ve moved on from it. And so has, fortunately, the attention of the pH๏τographers and the prying eyes on me. 

‘But I’ve had to learn to live in a certain way that keeps them at bay. And I have to handle my kids’ and my partner’s privacy in the same way.’

Sienna and Jude first met on the set of their film Alfie, and the pair got engaged on Christmas Day in 2004 after nearly a year of dating.

She broke off the engagement following news of his affair, with the pair separating in November 2006 after failing to salvage their relationship.

They reconnected in late 2009 when both starred on Broadway, with Sienna even spending Christmas with Jude and three of his children in Barbados, but they broke up once again in February 2011.

Before meeting Sienna, Jude was married to Sadie Frost -with whom he shares three of his children son Rafferty, 24, Iris, 20, and Rudy, 18- but they got a divorce in 2003, after six years of marriage.

Jude is now married to psychologist Phillipa Coan, 32, who he was first spotted with at the Hay literary festival in 2015.

The couple got married at Old Marylebone Town Hall in London in 2019, before partying in Mayfair – three months after the actor announced their engagement. They have two children together.

The actor also has a daughter Sophia, 15, with model Samantha Burke and Ada, nine, with musician Catherine Harding.
