Katy Perry and Ellie Goulding showed off their chic winter style as they led the celebrities attending a Chiltern Firehouse party on Friday evening.

Katy, 40, wrapped up in a cropped light brown argyle sweater layered over a brown poloneck, teamed with blue boyfriend jeans and adidas trainers. 

The Firework singer acessorized with a fluffy brown beret and a black crossbody mini-tote and injected a dose of glamour with a slick of cherry-hued lipstick. 

Ellie, meanwhile, showed off her toned figure in a pair of тιԍнт black leather trousers paired with a light brown cardigan. 

The 38-year-old singer – whose marriage to Caspar Jopling ended last year – wore her blonde hair in a tousled middle-parting. 

The stars were joined by a host of other famous faces at the exclusive London H๏τspot, including Karlie Kloss and her billionaire husband Joshua Kushner, Princess Eugenie, Sacha Baron Cohen and Glen Powell.

Lottie Moss and Rocco Ritchie also arrived at the venue later in the evening, with the party going on until 4am. 

Lottie exuded glamour in a black dress teamed with an opulent fur coat and diamond drop earrings. 

Madonna’s son Rocco went for a retro-style leather coat and gloves teamed with tailored grey trousers. 

Ellie’s night out comes after she reflected on the ‘hardest times’ she endured in 2024 in a New Year’s post.

‘Strange that the hardest times can exist at the same time as feeling the most alive,’ the singer wrote on Instagram earlier this month.

‘God you’re welcome, 2025. Love to my amazing son, the glorious women in my life and my fans.

‘Thank you for this and thank you all for your support, without which I wouldn’t be here.’

The video featured clips of Ellie on the red carpet, working out with a trainer, posing for pH๏τoshoots and enjoying downtime with her friends and family.

Ellie and her husband Caspar separated in February and the pair are now co-parenting their four-year-old son Arthur.

The Lights singer also recently split from her boyfriend Armando Perez.

The musician and the surf instructor – who is eight years her junior – struck up a romance when he gave her surfing lessons as she rang in the New Year in Costa Rica.

However friends of the pair told MailOnline that their relationship has now run its course.

One said: ‘Amando and Ellie were very attracted to one another. Despite the age gap, they struck up an instant chemistry when he gave her private surfing lessons.

‘They soon formed a bond and loved spending time together – Ellie loved hanging out on the beach with Armando to get away from everything that was going on back home after her marriage had come to an end.’

‘Armando was used to spending his days instructing in the water and running around barefoot in swim shorts, and was more comfortable enjoying his “quiet life” without the “drama” of being in the public eye,’ the source added.

‘They had a very special time together and she visited the country a lot. But they are from very different backgrounds.’

Ellie spoke out when pictures emerged of Ellie and Armando in swimsuits kissing pᴀssionately in the sea.

The mother-of-one made the decision to make public that her five-year marriage to Caspar, 32, had previously come to an end.

Confirming their split on Instagram, she wrote: ‘In light of recent stories, I feel I have been left with no choice but to let you all know that Caspar and I privately separated some time ago.

‘We remain the closest of friends and have been successfully co-parenting with our son’s best interests at heart.’
