Sadie Frost goes casual in joggers while cosying up to multi-millionaire beau Darren Strowger... as they join Jo Wood and her on-off boyfriend at glitzy birthday bash

They both have prolific hard-partying careers in their past.

And Sadie Frost, 51, was up to her old tricks once more as she joined fellow veteran party girl Jo Wood, 61, to help celebrate perfume designer Azzi Glasser's birthday at a glitzy bash in London's Quo Vadis restaurant on Saturday night. 

The glamorous duo were joined by their respective beaus, with Sadie draping herself around her multi-millionaire Darren Strowger and Jo joining her on-off boyfriend builder Paul Scarborough.

Her love... Sadie Frost, 51, was up to her old tricks once more as she joined fellow veteran party girl Jo Wood, 61, to help celebrate perfume designer Azzi Glasser's birthday at a glitzy bash in London's Quo Vadis restaurant on Saturday night

Sadie formerly enjoyed high profile marriages to Spandau Ballet frontman Gary Kemp and later Jude Law, yet she has now found love with Darren, the chairman of technology giant Excell.

Shunning the glitzy gowns favoured by her cohorts, the lingerie designer proved she can still ooze high fashion while going super low-key. 

Opting for a sports luxe ensemble, Sadie sported loose-fitting black tracksuit bottoms with fine white piping, while pulling a bold crimson T-shirt over a plain black long sleeve top - making for a super casual feel. 

She boosted her height with leather ankle boots, with the style of the shoe contrasting heavily with the sporty look, as a trainer was possibly better suited to the outfit.

Showing off her ageless good looks, the stunning star sported minimal make-up with just a dab of foundation enhancing her glowing complexion and her bright eyes emphasised by a slick of mascara. 

Darren meanwhile went for a classic rocker style in head-to-toe black complete with a thin grey scarf while his long hair was pushed behind his ears. 

Jo, who found fame following her marriage to Rolling Stones rocker Ronnie Wood, was equally casual as she wore jeans with a poloneck black jumper.

In her nature... Fellow glamorous additions to proceedings was singer-turned-fashion pundit Brix Smith Start, who looked typically well-turned out in a sheer black gown

Ensuring she added some sparkle to the look, she pulled a glimmering kimono over the top, with beaded embellishments along the chest and wrists. 

Paul, who first met Jo when he carried out renovation work on her £3million north London townhouse, kept things simple in a charcoal V-neck jumper with a black T-shirt layered underneath. 

Birthday girl Azzi ensured all eyes were on her during the bash as she slipped into a stunning emerald green gown with spaghetti straps and a Bardot detail.

Goth: Fashionista Nikita Andrianova looked extremely edgy in an all black look which was perfectly paired with her charcoal grey bob and slick of dark lipstick

Sparkling star: Jeweller Lara Bohinc went for a casual look while rocking spiffy red leather trousers 

The dress boasted a floor-sweeping hemline and a racy split extending the length of the leg yet she dressed things down with a pair of leopard print ankle boots.
