Matt Smith looked like he had a night to remember at Chiltern Firehouse.

The Doctor Who Alum, 42, arrived stony-faced but left looking happier than ever as he let his hair down and partied until 4am on Thursday morning.  

For the outing, he kept things causal in black jeans and a navy ʙuттon up jacket over a simple white top.

He added to his simple outfit with a pair black boots and kept warm with a navy Barbour coat.

The actor finished his look with a black and white scarf, which he seemed to have acquired during his fun night out.

The celeb H๏τspot in Marylebone boasts a nightclub, restaurant and H๏τel and was once the area’s fire station until 2005.

It comes after Matt packed on the PDA with a mystery woman while on holiday in Rio de Janeiro last month.

The star was seen locking lips with an unknown brunette before the couple also embraced.

Standing with their arms wrapped around each other, the pair appeared to be catching up with friends for the day as they enjoyed their time in Brazil.

The actor attempted to keep a low profile as he hid his face beneath a backwards white baseball cap and stylish shades.

He completed the simple look with a white T-shirt, baggy blue shorts and black sliders.

Meanwhile his mystery woman kept it chic in a summery red dress and brown woven bag as she cosied up to the star.

Matt is currently thought to be single after ending his most high profile romance with Lily James back in 2020.

MailOnline have contacted Matt’s representatives for comment.

But fast forward many hours later, the actor looked a lot happier as he left the swanky nightclub

The couple first met in 2014 on the set of Pride and Prejudice and Zombies in which Smith played Mr. Collins and James Elizabeth Bennet.

It was previously reported by The Mail On Sunday that Matt was dating businesswoman Caroline Brady in 2021 but they have not been pictured together since 2022.

Lily and Matt were notoriously private about their relationship before going official at the Milan premiere of Lily’s film Cinderella in 2015.

She later quashed rumours of a proposal, telling The Sun on Sunday: ‘We’re not engaged yet. But it’s going very well.’

The pair split in 2019 owing to ‘hectic’ work schedules before briefly rekindling their romance during the first Covid lockdown in which they self-isolated together at the north London home they had shared.

However, they split for good in October 2020, with sources claiming they ‘realised they’d be better off as friends.’

Before that he dated several famous women including Billie Piper, Brazilian actress Mayana Moura and model Daisy Lowe.

In July 2023 Matt was spotted in a clinch with actress Emma Laird, 24, outside a pub near his North London home.

The couple spent hours chatting and laughing together, and at one point they were seen gazing into one another’s eyes as they drank and smoked at a picnic table.

And at around midnight, the pair headed off into the evening together. An onlooker said: ‘They were both looking in great spirits, enjoying several drinks al fresco until the late hours.

‘They seemed to have great chemistry, and once the lights were switched off, they disappeared together.’

Just a month later in August of that summer Matt enjoyed a cosy date with his rumoured girlfriend Lili Gattyan at a restaurant in Marylebone.

An onlooker told The Sun at the time: ‘They appeared close and were laughing and joking. He had his dog with him and people stopped by for a chat.’

Lili, who owns a swimwear brand Eunoia, ‘looked like she was having a ball’, added the onlooker.

MailOnline contacted a representative for Matt Smith for comment at the time.
