Adele’s floor-length gown was cinched around her waist with a chunky black leather belt, which highlighted her hourglass physique perfectly. 

The songstress worked her blonde locks up into a sleek bouncy ponytail, and added further glam with a pair of statement silver cross earrings. 

Adele accentuated her pretty features with an expertly-applied coat of make-up, including a shimmering bronze eye shadow and a pink lip.

It was reported in June earlier this year that Adele’s Reformer Pilates class has given her a new lease of life as she has lost more than a stone in weight after attending the workout with pal Ayda Field.

A source told The Sun: ‘Adele has been out enjoying herself and she sees that as her priority at the moment, along with being a mum to Angelo.

She has been loving her new workout regime and it really works for her.

‘It’s a bonus that she has shifted some weight. Her mates are glad she’s letting loose and there’s nothing but good feelings towards her. She’s got a new lease of life.’ 

Later in the evening, Adele was pictured sneaking out of the very star-studded party, where she rubbed shoulders with the likes of Diddy, 49, Future, 35, and Chris Brown, 30, at the exclusive hotspot. 

But there was no sign of Adele’s rumoured new boyfriend, Grime artist Skepta, 37, – the pair are said to have been on a string of dates following her split from husband Simon Konecki, 45.

Back in February it was reported that the superstar pair visited a vape lounge and rented out an entire 32-lane bowling alley in Studio City during a night out and ate at Jerry’s famous deli. 

This came months after the singer made an unexpected appearance at his show.  

In October last year, Drake, who refers to himself as Champagne Papi on social media, was said to be thrilled after Adele watched him perform at a Los Angeles show without his prior knowledge.

Taking to Twitter shortly after his performance, Adele raved: ‘Oii Champagne Papi blew my mind tonight! Best production I’ve ever seen hands down and way up there with one of my favorite shows of all time. Huge love.’

Returning the compliment, a clearly stunned Drake later thanked the singer after reposting her tweet on Instagram.

Captioning the post, he wrote: ‘Oiiiiiii don’t f***ing get me gassed right now I love this woman and she came to the show. Thank god nobody told me I would have been SHOOK (sic)’

The pair are understood to have enjoyed a firm friendship on social media before meeting in person, with fans often calling for them to collaborate. 

On Monday, RiRi celebrated with Drake at another of his birthday celebrations, held at Poppy nightclub.  

In 2018, RiRi famously spoke to Vogue about her on-off former lover, Drake, ‘We don’t have a friendship now, but we’re not enemies either. It is what it is.’ 

An E!News source said: ‘The pair, ‘looked like they were having fun together as friends’ in the club.
