Lady Mary Charteris was spotted partying into the early hours of Friday morning with the likes of Noel Gallagher, Joe Jonas and Charlotte Tilbury at a star-studded bash in London.

The 37-year-old DJ had a night off the decks to let her hair down with the famous  group, as they were pictured heading to a karaoke night in West London.

The A-list crowd descended on an exclusive Notting Hill pub night of live music, drinks, and of course – singing.

The London socialite commanded attention in an ab-flashing cropped top, which showed off her toned figure.

Mary had a pair of flattering low-waisted jeans on, with a cool ring detailed belt.

A faux fur coat was slung over her shoulders to keep the chill at bay, with some pointed heeled boots peeking out under her jeans.

Joe was also spotted outside the venue, wearing a stripy knit jumper, a leather jacket and black boots.

Last year, Mary revealed she went sober – so there’s no doubt she enjoyed a night free of alcohol with her celeb pals.

At the time, she took to Instagram to share a snap at the launch party of a non-alcoholic sparkling rose by Della Vite – the brand created by sisters Chloe, Poppy, and Cara Delevigne.

‘Finally something for the non drinkers,’ Mary wrote. She added: ‘I haven’t drunk for six years, five months and 22 days but who’s counting. I’m always looking for other options when I’m out.

‘Thank you Della Vite for catering to everyone. And thank you for having me to DJ the launch of your zero alcohol Prosecco.

The youngest Delevingne sister, model and actress, Cara, 31, who previously checked herself into rehab after struggling with addiction, has also appeared to take a liking to the tee-total beverage, and clutched a bottle of it at Glastonbury.

Mary shared snaps of her DJing at the launch party – one of her many creative talents, with her also being a member of electronic rock band The Big Pink.

She was once known as a wild party girl. Now, the model/DJ/singer/IT Girl, continues her fun-filled endeavours, but booze-free.

She contributes to a list of young socialites opting for a tee-total lifestyle.

Last month, Mary attended an exclusive foodie event in Mayfair, where she DJ’d.

According to the Evening Standard, the Royal Ascot welcomed a net value of 28 Michelin stars with the flurry of chefs which cooked at the revered racing event this year.

The star-studded roster included Yannick Alléno and Benoit Blin.

Meanwhile, others on the roster were Simon Rogan, Tom Shepherd and Saturday Kitchen’s James Tanner.
