Alexa Chung stepped out wearing bridal white and flashing a ring on her wedding finger as she attended Paris Fashion Week on Tuesday. 

The model, 40, first sparked engagement rumours with her boyfriend Tom Sturridge back in June, with the couple seen wearing matching rings in October. 

Posing for photos ahead of the Christian Dior Fall/Winter 2024-2025 ready-to-wear show she teamed a plunging satin blazer with matching high waisted trousers. 

Alexa topped off her elegant outfit with a pair of black patent loafers and carried a bouclé handbag from the designer. 

She styled her hair into tousled waves and opted for a subtle makeup look with a dusky pink lipstick. 

Back in June Alexa, was spotted with a ring on her wedding finger, leading people to speculate that they are engaged.

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.'

Her spokesperson declined to comment when asked about the rumours.

Tom and Alexa went public with their romance last July 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 Miller, 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'.

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.

'This year everything exploded with Tom in London and Sienna leading a separate life in the US and [her appearance at] Cannes'.

Alexa meanwhile has enjoyed a slew of high-profile romances.

Her exes include Alex Turner, Alexander Skarsgård, Orson Fry, Albert Hammond Jr., Faris Badwan, Faris Badwan and Theo Hutchcraft.

In 2018, she spoke to Porter about marriage, saying: 'I just don't get why marriage is different from non-marriage — I just don't get it … I think having a partner in life must be quite nice but I don't need a wedding day per se'.
