Lily Allen exudes elegance in a classic little black dress while dripping in diamonds as she performs at De Beers event during Paris Fashion Week

Lily Allen was the picture of glamour on Tuesday night, as she draped herself in diamonds for a De Beers London bash, held at Hôtel d’Évreux during Paris Fashion Week.

The singer, 40, slipped her svelte frame into a chic black minidress with a sophisticated off-the-shoulder neckline, leaving her long legs on full display. 

While she ensured that all eyes were on her by accessorising with a slew of dazzling diamond pieces, including a huge sparkling ring, chandelier earrings and a statement necklace that hung down her back.

Completing her striking look, Lily added a pair of leather evening gloves to give her elegant outfit an edgy touch and swept her hair back to showcase her array of jewels.

The West End Girl hitmaker treated the star-studded crowd of attendees to a special live performance, followed by DJ sets from Agathe Mougin and Sydney Lima.

She looked to be having a blast at the lavish event, laughing alongside actress Chase Infiniti and models Jodie Turner-Smith and Adwoa Aboah, as they took turns showing off their stunning jewellery pieces.

Despite Lily arriving at the party solo, she was later seen leaving the venue alongside her new love interest Jonah Freud.

The writer, 28, was spotted following her as the pop star made her stylish exit, wrapped up in a black leather trench coat.

She has been getting close to Jonah, who is the son of entrepreneur Matthew Freud and ex-wife Caroline Hutton and the nephew of celebrated late artist Lucian Freud, since last year. 

Their newfound romance comes after the breakdown of Lily's marriage to David Harbour, 50, which inspired her hit album, West End Girl.

She and Jonah have been spotted on multiple dates and recently took things to the next level by jetting to Rome together for a mini-break.

The couple reportedly stayed in a suite at the Hotel Locarno, thought to cost around £800 per night, and were spotted on a coffee date outside the Sant' Eustachio Caffè in Rome. 

A source told The Sun: 'We walked past her and it was my daughter-in-law who recognised her and went, "Oh my God, it's Lily Allen."

'We did a double take, and it was definitely her, she was with Jonah Freud. They were just having a coffee and a cigarette together.

It came just weeks after the pair were spotted kissing at her celeb-packed Christmas party at London's Stringfellow's last month. 

Lily and Jonah had their arms around each other in several photos before they were pictured sharing a kiss in front of the rest of the guests, in snaps acquired by TMZ. 

The confirmation of their romance came followed weeks of speculation surrounding the pair, after they were spotted enjoying a cosy-looking dinner date in a west London restaurant.

The pair looked cosy while chatting and laughing over dinner at the Michelin-starred Dorian in Notting Hill. and are said to have spent more than two hours together before leaving the venue separately.

Lily - who is an old friend of the Freud family - and Jonah were also pictured together back in September at an Oasis party held at the Chiltern Firehouse.
